I like accu-clear it is a great tool to clear tanks of cloudy water caused by organic material and waste, about 20 drops per ten gallons. I use this when the amount of waste between tank cleanings clouds my water. Which is rare to begin with, but when I am crunched for time and have company coming and dont have a chance to clean the tank, and it doesnt seem to affect my waqter parameters too bad, I highly reccomend it.
That stuff rocks, I used to use it all the time. My tanks have been staying pretty clear on their own no
