I was amazed how well and fast those cube works. My water has never been clearer I believe it also works on the smell because my fish tank does not smell any more
This block works great. I was battling algae in my tank every week it was thick with it. I was having to do complicate water changes every week and Scrubbing the sides and everything in the tank. This block took care of that now I can do partial water changes and my fish are happier for it.
Clarity in fish aquarium
Absolutely cleared my tanks! Salt and fresh! Love them! I will be a permanent customer!
Works great.... I'm ordering another one for my other tanks.
