So happy!

Fantastic regulator I could not be more thrilled with. Ive used many other brands of co2 regulators for my planted tank and reef tank, but GLA takes the cake when it comes to co2 systems.

Great kit and fantastic service

This Gro system has exceeded my expectations by a mile. For a complete system with cylinder this kit is hard to beat. Its backed by GLA full customer support system which as a newbie I was totally grateful for. My 75g tank is a showpiece in my house and the topic of discussion every time we have guest. Its the GLA co2 system that really propels the discussion in my home when guest see it. It looks very sleek,clean and neat. Its perfect for the compact space I have under my 75g tank. I do love this regulator:)
