Works as intended - 0 nitrates
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.

Helps to stabilize newer aquariums quick!
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.

Chicken or the egg?
Hard to say if this really did anything for my aquarium. I added this to a fairly new setup that was having some cloudiness and it eventually got clearer but results werent overnight. With that said, it's hard to say it's because I added this.

great for shrimp tanks
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.

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