GLA Pro1

This regulator has never given me a single issue. I'm actually just here to buy another modular block because I'm setting up a new tank. Disclaimer: I've begun to have a growing love for mechanical things with no overlying software to introduce unreliability for no discernable reason. I've begun my decent into grumpy old man. I bought this thing here about 4 years ago ,got a filled 20 lb CO2 tank from the hydro store ,hooked it up to a 20 long, plugged it in and it's still running on the same cylinder ( the tank readout needle has barely moved) without a hiccup as I write this. It's nice to spend the extra money on a something and be more than completely satisfied with the purchase. To me this is a no brainier, high quality, made in the USA and between it's reliability and the fact that after dial in with nutrients, I don't even think about algae anymore , if you're on the fence get off of it.

Pro definitely describes this regulator

From packaging to instalation everything was full proof. The regulator was packaged in a box along with other items i ordered using form fitted foam. Nothing was damaged in transit do to this style of packing. They give you step by step instruction to install this regulator correctly that are easy to follow. I also got a couple of GLA tools with my order and the quality was outstanding. The real difference between GLA tools and Amazon tools are the quality and the comfort when using them.

I will never spend money on an Amazon regulator again. Spending a little more on a quality regulator will save you money in the long run as i have had cheaper regulators fail time and time again.
