How often do I need to use this?
Answer by ChewyDec 07, 2017
There is not a specified time period to use this Water Clarifier. It will be dependent on a lot of different variables regarding your tank. Your tank may become cloudy close to a water change, or overfeeding your fish or a filter not working properly, etc.

How much of this do i put for one gallon?
Answer by ChewyMay 30, 2021
For a tank that small, we recommend small water changes daily until it clears up, usually. Small tanks require frequent small, partial water changes and the dose would be miniscule - 1 or 2 drops.

Is this safe for Batta fish?
Answer by ChewyOct 27, 2020

Watch out

I used this as an alternative to other brands to clear up cloudy water problem. It ended up killing a shark and a plecostomas fish. Both of which are bottom feeders. Im not sure what happened, but when I took the fish out, they looked as tho this product gave them chemical burns. Other fish In the tank fins look rough. Im not sure if they will make it. I have a 20 gal tank that has been established for 4+ years. Things are labeled on the side for easy measure. I doubt I over did it. I wouldn't recommend this product something isn't right with the mixture or batch. And on top of it all the water isn't even fully clear.
