Easy to use, works great to clear water up, and good size bottle.

### ⭐⭐⭐⭐⭐ Will clear water but needs a little help
*by P***F on March 20, 2021*

This is a fairly inexpensive product that really works and helps to have particles bind together to be big enough for the filter to grab. I had nothing bad happen to my plants or livestock using it, including fish, snails and shrimp. Keep in mind this will make the water very cloudy at first but this goes away within 24 hours. Also understand that for this to work some kind of polishing pad will be needed in the filter. A coarse sponge just isn't dense enough to trap the particles even with this product. Buy something that can be cut to size and either placed in the bottom of a canister tray or cut to the size of the plastic on a HOB filter. Just cut off the filter pad on a used one and put this on instead when needed. One more thing to remember is this will bind up floating algae and if it is dead it can be removed. Green algae clouding the water will reproduce faster that it can be removed so you have do deal with that and let this and a polishing pad clean it up. Usually a UV sterilizer will work to kill it and it won't come back as much once the tank matures and nitrates come down. It is good to keep on hand for times when people are coming over and you want the tank to be clear to show off!
