    Excellent product worked great for my RO water.

    I was using liquid based GH additives prior but that did not seem cost effective for my 200g tank. I started using GLA GH Booster and my tank is totally stable. I add this to my RO water holding tank that houses a heater as well. The water is constantly circulated to ensure perfect mixing. The easy to use jar makes dosing a breeze and keeps everything dry.
