Brightwell Aquatics MicroBacter7 Biological Filter Bioculture Aid, 250 ml

This stuff works as intended. I will be honest, I thought this was a type of bacteria to boost bacteria biodiversity, and technically it is but it is mostly an enzyme to tackle nitrates in your tank. Ever since I've dosed this my tank has stayed at 0-.1 nitrates which can be good at times. But some nitrate can help foster coral growth. And ever since I've dosed this, my corals haven't grown as fast as they used to. So I would say this product is great for when your tank has been established and you want to "freeze" your tanks growth. But for new tanks I would stay away for awhile and instead buy brightwell clean which has the bacteria to broaden your bacteria biodiversity. The enzymes in this product eat at the nitrates and turn it into nitrogen gas which completely eliminates nitrates so if you want some nitrates, use this product with caution. But if i had done my research and used this product as intended, it did exactly what it was meant for.

Been struggling to get my nitrite values normalized using API Quick Start. It’s Day 3 of using MicroBacter7, and my values are in a safe range. Water is clear and my fish are happy. Great product, will continue to use this from now on! Highly recommend.

This product got my shrimp tanks cycled in two weeks. I'm now two months into shrimpkeeping, and my shrimps still prefer to eat the biofilm on the hardscape over hikari algae wafers or even bacter ae.

Excellent product. Thank you so much 🙏

I’ve had great success with Brightwell products so far and decided to try this to help with my battle against nitrates and phosphates. Using every professional trick in the book and I see this helping slowly to make minor differences. My water clarity was already good so I can’t see a difference there. Hopefully by the time I’m done with the full bottle I’ll be in a good place with my NO3 & PO4!

This is helpful for keeping water clean and fish healthy.

Hace bien su trabajo

Literally everyone with an aquarium should own this! Without question better than seachem, fluval or any other bacteria seeding additive. I’m so glad I found this at a locally owned store when I needed it most. They also have one with starter bacteria. If I could give any aquarist one piece of advice it would be to buy this product!

com produtos deste genero , acabamos por nunca saber se funciona ou nao. nao vi nenhum tipo de mudanças no aquario ou nos corais...

This product arrived just over 24hrs ago and I am really impressed with it. Its several different strains of helpful, safe bacteria in a bottle. So won't harm fish, coral, sponges, anemones, worms etc or the bacteria in your live rock and filter. After a small water change and quick syphon of the really bad parts of my sand I used this as directed on the bottle (remember to turn protein skimmer off for 4 hours). I did this late at night so went to bed. The following morning I woke up to a pristine tank.. it looked brand new inside! Water looked clearer, fish looked brighter and corals etc looked healthier. I was recommended this by a friend to use alongside Microbacter Clean regularly and their tank is now crystal clean and healthy. So will definitely be using this for the foreseeable..

منتج في نظري ضعيف استخدمته للحوض البحري وهو بطىء

I have used it for bring my nitrifying bacteria population and it did what I have expected. I strongly recommend it and will keep on buying this product.

This product doesn’t work. Nor bacteria growth. I have been using it for a more than a month and nothing happened.
