GH BOOSTER
I don't know about the "ultimate". But, it does exactly what I need it to do. It's consistent and it's available. 3 days after my order it shows up on my doorstep, packaged well (with a couple items I can't tell the W...hgoghmf about).

Best RO remineralizer.
I’ve been using GLA GH Booster for over a decade. I’ve used it for both my freshwater and reef tank. It’s always on point when I check my TDS or GH without fault. I love the new jar as well, makes it incredibly easy to dose and no mess. Love ❤️ it!

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.
