Great item
Have used this product religiously on my water changes and don't ever see that changing

Useful for starting a new tank
It simply replaces all those starter kits as you can double the dose for a new aquarium to boost the biological filter. What a brilliant product! My guppies are happy with this.

I use this weekly, RELIGIOUSLY. I do not miss a dose. This is my tank today, having not touched the filter in 18 months. (Fluval FX6 filled with only biohome filter media and polishing sponges.) I’ve only changed out the live plants when needed (pothos houseplant clippings) and used the magnetic algae glass scraper when needed. It’s a 75 gallon tank. I8 MONTHS!!! I highly recommend this product. Zero odor, zero nastiness.

I was having some issues controlling nitrites. Used it, two days later, down to zero and stable. I don't see any issues with my Ph, fish, snail, shrimp and plants. I'll keep dosing the water as instructed.

My regular go to solution after water change.. this has helped my ponds as well as big tanks for maintaining good bacterial colonies in sump and canister filters
