Sentry AQ Mardel Brite Nâ?? Clear, 4-Ounce

I used this in a 45 gallon tank, and in a 56 gallon tank. The directions say to dose the tank, and that you can repeat after 6 hours, if needed. I used it and within a matter of an hour or so, the tanks were both sparkling clear! This product is great!

I got the product as ordered in a timely manner but it just didnt work in my fish tanks
