Very Effective
I’ve been using this for 6 months and I’m impressed with how well it works. When I do partial water changes, pulling water from the gravel, I get water that’s a little darker than new water, but there are no visible particles and no cloudiness. Whatever this is, it does a great job of breaking things down

Amazon Customer –
Wow, works like magic. used it for my two goldfishes, they sure know how to make the tank dirty, my gravel cleaner couldn’t even pick up all the poop they made. two days after using this. the poop disappeared.. i can barely see any left at the Botton of the tank and the water looks clearer. my goldfish now can dig through the gravel without accidentally eating their poop but leftover food.
