Complex system of non-pathogenic aerobic and anaerobic microbes, as well as natural enzymes, specifically formulated to establish biological filtration in new aquarium set-ups, and to enhance the rate of nitrification, denitrification, and organic waste degradation in marine and freshwater aquaria through complete nutrient remineralization.
Benefits are:
1. Rapid reduction of organic carbon, ammonia, nitrite, nitrate, and phosphate. 2. Digestion of uneaten/undigested food, excreta, detritus, and other latent organic material, resulting in cleaner and healthier aquarium substrate (without having to physically clean or disturb the substrate bed). 3. Reduction of organic compounds into nutrients that encourage the growth of photosynthetic organisms (e.g. zooxanthellae, macroalgae, plants). 4. Greatly-reduced hydrogen sulfide production. 5. Increase in dissolved oxygen concentration. 6. Limits availability of pre-existing phosphate to undesirable forms of algae and cyanobacteria. 7. Increased water clarity.
Supplied in a state of suspended animation for maximum longevity.
Formulated utilizing extensive data compiled by microbiologists.
Technical Background The concentration of dissolved and particulate organic materials in any aquatic environment can have a significant impact on the overall appearance of, as well as the health of organisms residing within, that system. Relatively low-nutrient environments are characterized by high water clarity, lack of unpleasant odors, and absence of microalgae and cyanobacteria; this is collectively a result of the lack of nitrogen-, phosphorus-, and carbon-based waste available. Aquaria that are relatively rich in available nutrients have characteristics opposite to the afore-mentioned, and are typically not desirable because of the resultant appearance of the system and the difficulty of maintaining healthy aquarium inhabitants. Brightwell Aquatics MicroBacter7 is a selective complex of extremely effective microbes and enzymes that rapidly reduces the concentrations of organic nitrogen, ammonia, nitrite, nitrate, phosphate, and organic carbon in all marine and freshwater ecosystems, leading to greatly improved water quality; better water quality typically leads to healthier aquarium inhabitants. MicroBacter7 does not require refrigeration, however storage in a cool, shaded area will prolong the activity, and maximize the shelf-life, of the product.
Instructions and Guidelines: Shake product well before using. Mix appropriate volume of MicroBacter7 (see below) with 250-ml (~8 fl. oz.) of aquarium water in a clean container prior to addition to aquarium. If using a pipette to dispense MicroBacter7 below water level of container or aquarium, be sure to thoroughly clean pipette with fresh water prior to placing tube back into MicroBacter7 bottle; failure to do so will contaminate the product. Best results may be obtained by adding mixture to external biological filtration system (if applicable). Do not add to pump intake port(s). For best results, use within 1-year of purchase date. Grossly overdosing MicroBacter7 will not significantly increase the effectiveness of the product, nor the rate at which it enacts changes in aquaria. The following recommendations are based upon extensive testing and will produce the best results in most aquaria.
Medium- to High-nutrient Systems, or to seed Biological Filtration in new aquaria: To effectively decrease the concentration of available nutrients and waste material in all marine and freshwater aquaria, add 5 ml (1 capful) per 25 US-gallons (94.6 L) [˜4 drops per gallon (3.8 L)] of aquarium water daily for the first two weeks of use; the impact that MicroBacter7 has on an aquarium is most evident within this period. Turn protein skimming and UV-sterilization off for a period of 4 hours following addition to aquaria. A noticeable difference in water clarity is typically apparent within 30-minutes of dosing. Follow same instructions for new aquarium start-up. Thereafter, switch to “low-nutrient” dosage (below).
Stable, Low-nutrient Systems: To maintain a low concentration of available nutrients in all marine and freshwater aquaria, 5 ml (1 capful) of MicroBacter7 per 50 US-gallons (189.3 L) [˜2 drops per gallon (3.8 L)] of aquarium water no more than once each week; alternately, add 1 drop per 50 US-gallons daily (or 1 drop per 25 US-gallons every other day). Turn protein skimming and UV-sterilization off for a period of 4 hours following addition to aquaria. Dosage may be adjusted according to perceived benefit to aquarium, however it is recommended that the dosage not exceed 1 drop per 10 US-gallons per day. With time, hobbyists may determine that decreasing the dosage and/or dosing frequency by up to 50% sufficiently maintains a low-nutrient environment. During changes in biological filtration or when increasing the aquarium bioload, dose 1 drop per 25 US-gallons daily for one week, then resume “low-nutrient” dosage.
Caution: Keep out of reach of children. Not for human consumption.
Ingredients: Purified water, proprietary blend of natural enzymes and non-pathogenic, beneficial microorganisms.

I used this to cycle an aquarium with non-live sand, and uncured live rock. The tank cycled in a little over a week with only one water change. I still do monthly additions of MicroBacter7 as I am still stocking my tank. I couldn't ask for the product to do anything more
I’ve got a solid tank that has been cycled for going on two years. I bought this as a whim as I noticed my fish don’t eat all of the food given to them if it falls to the floor, though the snails get it. Overall, I’ve had good luck with helping control nitrite levels the tank with this product...Read More
I’ve got a solid tank that has been cycled for going on two years. I bought this as a whim as I noticed my fish don’t eat all of the food given to them if it falls to the floor, though the snails get it. Overall, I’ve had good luck with helping control nitrite levels the tank with this product, and it seems to have a beneficial affect for my plants competing against algae.Hide
Been using for 5 days now and I haven’t noticed anything yet, I used this product to help with preventing an algae bloom in my newly established tank. We will see in these coming weeks. I only rated 4 stars cause I don’t know if it works yet. I will update down the road.
