NT Labs Aquarium Cleaner Sludge Remover

The sludge in my tank was getting out of hand, so I gave this a try after a water change. Within two days the gravel looked noticeably cleaner and the water seemed clearer. Just wish the bottle was bigger for the price, but it did exactly what it promised.

I was skeptical about another bottle of sludge remover, but this one actually cleared the mulm off my plant roots within two days. It’s easy to dose straight from the 100ml bottle, and I haven’t seen any cloudiness in the water since.

My tank's gravel finally looks clean again after just one dose—no more brown patches where the filter misses. The 100ml bottle handled my 60L setup easily, and the water stayed clear all week.
