This is one of the easiest, and fastest acting clearing products I have used in my fish tanks. Just drop it in (after removing the carbon filter), watch it fizz away, and the cloudiness in the water is gne! The water can turn purple for a few hours at times - which is a little strange looking, but clears up shortly. One tablet per 10 gals of water. I recommend this for anyone from the novice to the experienced hobbiest.

Pros: Fast acting and easy to use

Cons: Must remove carbon filter before using

This products works really fast to get rid of cloudiness in your tank. It's usually the second day after cleaning that I get the cloudiness - just a drop per 10 gallons clears it up!

Pros: works fast

Cons: none

use in our tanks

Pros: na
