Healthy Earth Man Eats Up the Bad Guys!

Mico Heroes – Microbes Eating up Bad Bacteria

Nature has a rich aquatic ecosystem system with water self-purification. In polluted water with sludge accumulating at the bottom and foul odours, self-purification power decreases as the result of the dominance of putrefactive microbes. This leads to decrease the nutrition necessary for ecosystems to function and keep their purification.
This holds a dominant position in the layer of the microbes and helps ecosystems revive and reduce sludge and foul odours. The purpose of this application is not to create apparently-clear water by chemical means but to revive the native function of the aquatic ecosystem. Depending on the overload of drainage and the volume of water, the amount and the frequency of Application varies depending on the condition of the water, you will need several weeks or several months to fully recover.

Water Gardens and Ponds

Note: US gallon= 4 litres

Water gardens and small ponds offer a valued aesthetic attraction to the home or business. These pools can develop their own ecosystems that can easily go out of balance. If the water is left stagnant for too long, mosquitoes will start to inhabit the area, algae begins to form in the water, and odours can start to appear. Adding in a feature that circulates the water can cut down on these problems, but depending on the water quality, algae and calcium, deposits may still form.

Using Micro Heroes Probiotic on a regular basis will help to keep nutrient levels low enough to prevent the growth of algae. Also has the ability to neutralize salts-which can act as a natural chlorinator-and prevent them from crystallizing on pool surfaces.

The monthly application ratio is 1:10,000, which is 1 part Activated EM on how to make it for every 10,000 parts of water). It is recommended that this dosage be applied in weekly increments, rather than all at once. The water temperature should be 5 F degrees above freezing. Allow several weeks for the materials to do their work. Some sludge from the bottom will likely surface creating an unsightly scum. Leave it and let nature do its work – as it will disappear soon. This method could work well also with a larger pond or lake clean up.

Hot Tub and Swimming Pool Applications

Skin irritation and sore eyes? Conventional treatments attempt to use antibacterial approaches for creating a sterile environment in the water. This antiseptic approach of destroying all bacterial life in the water often makes a bad situation worse. Healthy and beneficial micro flora is what sustains biodiversity in our environments and help to build natural defense systems. Using Micro Heros Probiotic to naturally remediate the water helps to keep nutrient levels low enough to prevent the growth of algae, and acts to keep the water micro structured – which is soothing to the skin. There are a variety of factors which contribute to maintaining clean and healthy water quality systems – such as climate, evaporation, temperature, and frequency of use.
Application rates depend on frequency of use. If the swimming pool or hot tub is used on a daily basis, should be applied every 3-4 days. If they are used moderately, then apply every two weeks. If used infrequently, then apply once every month. Swimming Pools is 1 part activated enzymes to 10,000 parts water. For a swimming pool that is 20,000 gallons in size, the application rate would be 2 gallons. One cubic metre of water will require one kilogram of ceramics and should amount to one thousandth part of the water mass and used with liquid EM. Where larger and constant masses of water are concerned, the amount of ceramics can be reduced by ten to twenty percent. Hot Tubs – the application ratio is 1:2500. So for the average size hot tub of 500 gallons. One cubic metre of water will require one kilogram of ceramics and should amount to one thousandth part of the water

Aquariums and Fish Ponds

Water quality management is crucial for keeping aquariums healthy and clean. Fish droppings and residual foods also pollute the water. It is recommended that this dosage be applied in weekly increments, rather than all at once. When changing the water, it may be best to change approximately half of the water on a regular basis. Mix the AEM Before adding the replacement water at a ratio on 1:1000 every month to help remediate the water. This would be ¾ of a teaspoon per gallon of water or 1 ounce for a ten gallon fish tank. If your tap water is chlorinated, let it sit overnight in a large container in order to allow the chlorine to off gas  – promote the micro-structuring of the water – one bag for every 10 gallons.

Recipe for Making Activated EM (AEM)

Can be activated to approximately 20 times the original amount. This is definitely not necessary, but it is often done to save money. It also helps to awaken dormant microbes. Application rates are the same either way.

Ingredients (per 1L):
  • 1 part Probiotic EM (40ml)
  • 1 part Organic Blackstrap Molasses (40ml)
  • 1/4 tsp Ceramic Powder (optional)
  • 20 or (800ml) parts de-chlorinated water*, not distilled or reverse osmosis or highly recomendedt to use structured water (from EM ceramic ball or K pipes)

Clean, airtight bottle (1L), generally plastic with screw-on lid (not glass) – can use bigger jugs, too. (do not use a jug in which a bad batch has previously been fermented, unless it has been washed, scrubbed, and cleaned with Probiotic EM, and then all of these steps repeated again) pH paper is very useful to determine if your batch is good Note: De-chlorinated water is not necessary, but definitely beneficial, as chlorine kills microbes. Tap water can be de-chlorinated by letting it sit out for 24 hours.

  • 1. Heat some of the water to 115-125F
  • 2. Pour water into your bottle and dissolve molasses
  • 3. Mix in the ceramic powder and then mix with the Probiotic EM
  • 4. Add the remaining water and stir and/or shake very well.
  • 5. There should be an airspace equivalent to about 10% of the bottle on top
  • 6. Tighten lid and keep warm (95-110F is optimal) for at least 2 weeks, preferably longer**
  • 7. After the first few days, the container needs to be burped every day or two, as gases are formed that will expand the bottle. The mixture should be stirred and/or shaken daily for the first 3 weeks, too.
  • 8. Can be used when pH is below 3.9, but preferably below 3.7. It should also have a sweet smell (it may smell a bit when you initially take off the cap, but if that persists for more than 10 minutes of the cap being off, or if the pH is 3.9 or over, it should not be used.
  • 9. Product is better left for at least 4 weeks for highest benefits

Note: Can be kept warm in an oven with the oven light on (put a note on the oven), in a cooler with a terrarium heater or some other heat source, or many other ways. The whole process can be done at 70F, but it will take 6-8 weeks, and the odds of failure are higher. Even keeping it warm for the first few days is helpful.

Extra helpful techniques:

1. During the 2nd and 4th weeks of brewing, take the container(s) out of the heat source and let sit at room temperature for 2 days. This seems to help the fermentation process

2. Leave the lid off for the first 24 hours to encourage some air

  • 1. Probiotic EM stores for 6-24 months, or potentially a few years
  • 2. Activated EM stores for two months or potentially 2 or more years if it is a good batch. Cooler room temperatures will keep it longer (10-20C is optimal). Store it in the dark, with the lid tight.
  • 3. While it is good to brew it with a bit of airspace and stir/shake it daily during the first 3 weeks of brewing, it is best to store it after that without any airspace and without any more shaking if you want to keep it stored for more than a month. The odds are, if you are brewing it for long term storage, you are probably brewing many bottles at once, therefore one of the bottles can be used to top off the rest, and then the remainder in that bottle can be used first.

Note: Activating EM is not an exact science. As such, the occasional batch may fail to drop in pH to an appropriate level. You may try adding a bit more of the culture and other optional ingredients, or you may decide to throw it into the compost (or down the drain if it smells bad) and start again. Some of the
most common reasons for failure are:

1. Inappropriate containers (previously containing chemicals, putrefied food, bad AEM batches)

2. Poor water quality like: (distilled, reverse osmosis, polluted, very high in chlorine)

3. Filling the container too full during initial fermentation stages (best only 90% full)
4. Not optimal temperature (too hot or too cold)

5. Not burping and stirring/shaking daily

6. Trying to cheat by using more molasses than EM

When is Activated EM ready to use?

Activated EM is ready to use, 4 – 7 days after preparing it, when the pH drops below 4.0 (ideally it has a pH between 3 – 3.5), and when it has a sweet-sour smell and has changed colour from black to reddish brown.


AEM should be kept in an expandable air-tight container to keep it anaerobic. Store at room temperature between 20°C to 30°C (from 68°F to 86°F). Do not refrigerate. In containers that are not totally airtight, a white layer of yeast bacteria may form on the surface. Since this may lead to putrefaction, remove the layer as needed and transfer to a container that can be closed tightly. If it has a foul smell or the pH rises above 4.0, the solution could be contaminated with undesirable microbes and should be discarded. It is fine to pour this material on a long-term compost pile.

Making EM Bokashi Compost

Use a combination of organic materials with either a high or low ratio of carbon and nitrogen, e.g. wood/straw and grass. In order to increase the microbial diversity as much as possible, it is recommended that at least three different materials are used.
The method for making typical Bokashi compost is as follows:

1. Organic material (kitchen/garden waste) 100 litres (volume)

2. Dilute activated enzymes 200 ml with 10 litres of water

3. Dilute this AE solution slightly so that it can be mixed with the various fresh organic materials such as grass, weeds, shredded cuttings etc.

4. Heap the material up in layers and press down firmly so that as much oxygen as possible is released from the heap.

5. Finally cover the heap with a plastic sheet or a piece of carpet.

6. Leave this to ferment for at least six weeks before using the material as plant fertilizer.

NOTE: The final product is not composted but fermented. This means the AEM
will transform the heap into valuable fertilizer for ground and plants. The end result will not look the same as traditional compost but it is pre-fermented so that soil organisms can make optimal use of the material and there is absolutely no wastage which occurs from a rotting process.

How to make EM Mud Balls

Made of dried mud into which EM Bokashi and Activated EM have been mixed. They are used to clean up bodies of water such as rivers, lakes, and oceans where there are concentrated deposits of sludge and slime

Basic Materials:

• Dirt. It is usually best to use clay-like dirt that can easily be formed into balls.

• Activated EM

• Molasses (At 10% the volume of the AEM. For example, use 7 Tbs of molasses for 1 liter/quart of Activated EM.

• EM Bokashi.

• EM Ceramics Powder.

How to use EM Mud Balls

• Use in river bottoms and mud flats where slime has accumulated. Use one ball for each squares meter of surface area.

• Use once each season until results are seen.

• Cleaning up oceans, rivers, lakes and ponds requires the application of Probiotic EM into the water through a variety of methods. It is recommended that AEM also be regularly applied into the water to supplement the use of EM Mud balls.

Ratio of materials

• When using dirt only: 10 parts dirt + Activated E + EM Ceramics Powder

• When using dirt and EM Bokashi: 8 parts dirt to 2-4 parts EM Bokashi + AEM + EM Ceramics Powder.

• 8 parts dirt to 1-3 parts EM Bokashi + Special EM Bokashi for EM Mud Balls + AEM + EM Ceramics Powder.

• When using dirt and mud from mud flats: 5 parts dirt to 5 parts mud flat mud + AEM + EM Ceramics Powder

• When using dirt and mud from mud flats and EM Bokashi: 9 parts dirt to 9 parts mud from mud flats + 1 EM Bokashi + AEM + EM Ceramics Powder. Note: Since the water content of the dirt and mud used will vary, the amount of Activated EM will vary as well. As a general rule, though, if for instance you produce 3.5 – 4 gallons of material you will need approximately 1 litre/quart of AE. Always be sure to have enough AE on hand in case it is needed. If you use it up, you can add extra water instead (don’t be afraid to use a lot of AEM). Optional EM Ceramics Powder will be between 0.5 -1.0% of the total amount. For example, for 5 gallons of material this will equal 3.5 – 7 Tbsp of EM Ceramics Powder.

How to Make Bokashi

Ingredients: EM Probiotic (effective microorganisms) – some people try to save money by using their own microbe concoction. This does work to some extent but from what I see it looks like they get going with just the lactic acid bacteria. Yeasts may or may not be present and I pretty sure the photosynthetic bacteria are missing altogether. I recommend buying your microbes to ensure you get the three types of microbes including several strains of lactic acid bacteria, yeasts, and photosynthetic bacteria.

• Molasses – you can use either the type you’d find at the grocery store or the feed store.

• Water with no chlorine residues. You can use tap water as long as you leave it sitting out for at least 24 hours before using it.

• Wheat or Rice bran

• Mixing tub or tarp depending on how much you’re going to make

• Airtight container to hold your bran while it ferments.

• Time

Recipe for 10 Pounds of Bokashi

• 4T – 60 ml EM-1 or equivalent microbes

• 4T – 60 ml Molasses

• 10 cups – 2.5 liters water – no chlorine residues

• 10 lbs – 4.5 kg bran

Dissolve the molasses in the water. Add the EM microbes. Put the bran in a container big enough to hold it. Add the liquid and stir it up well with your hands. The mixture should be damp enough to hold together when you squeeze it into a ball but not so wet liquid is dripping from it. Adjust the moisture by adding either a bit more liquid or more bran.

Put the damp bran into an airtight container.A dark garbage bag in fine. Squeeze out all the air and fasten the top securely. Let it sit in a warm place out of the way for a minimum of two weeks. It’s okay to leave it longer.

There may be some white mold on the fermented bran at the end of the two weeks. This is good. If however the mold is black or green it means either some air got in or the material was too wet.

For storing long term dry the bran well. Ten pounds of bokashi would last the average family 6-10 months. Properly dried it can be stored for several years. Store in dark place

EM Ceramic Powder For Soils, Gardening or Farming:

Apply to the soil at the rate of 0.5Kg per Sq M/year. Sprinkle onto the soil surface and then gently rake in. About ¼ -1/3 teaspoon is added per gallon of water before using for making AEM

EM Probiotic for Odour Control

Mix one capful for 1 litre of water in a spray bottle. Use to eliminate odours for household and pets use, and for industry and farms.

EM Probiotic for Odour Control

Use to wash produce, bathrooms, kitchens, wash clothes and general cleaning.

EM Construction Care

Recently the issue of “Sick House Syndrome” has arisen, and there is a greater awareness of the materials used in construction. If one inhales fumes from paint, new building materials and adhesives, one can get sick. Mold and house mites are also a factor in this illness. With Probiotic EM and EM ceramic products, it is possible in the construction industry, to enhance the functionality, and toxic materials. The building’s durability will be improved, and in actual construction it’s been shown that the damage caused by adhesives and organic solvents can be reduced. At present EM and EM ceramics are being used in concrete in actual construction, and numerous buildings and houses have been completed implementing the use of EM Technology in construction materials right from the design.
