Great reactor

I opted to buy this reactor after I built one myself months ago. Although mine worked great, it required an external pump to power it, and it was massive. This GLA reactor is hooked to my eheim 2217, and runs like a champ. Came with everything needed, setup was very easy, and within 2 days, I had my co2 back up and tuned in. For reference, I have a 75 gallon tank, with high light, and pairing this with the GLA Gro-1, I think my setup will be bulletproof for months to come. GLA is making big waves in the industry.

Works amazingly well.

Im using this co2 reactor on my 75g tank and very pleased with its performance. Installation was a breeze with easy to follow diagram. Fits perfect next to my oase canister filter even though from what my friends say this reactor is of impressive size. It does have some volume you to it and I love the clear housing because you can see everything happening. What I like most with this co2 reactor is it requires no internal media,no bypass and no electric pumps. Its design alone gets all the work done with a cool whirlpool motion inside. Even my friends envy my GLA co2 reactor. :)
