Review on Gulfstream Tropical AGU00529 Ista Max Mix CO2 Reactor (Large) for Aquarium – Enhanced SEO by Cheryl Wilson

My favorite design. And my favorite price, great deal. I only had one small problem and I will mention it at the end. The flow from your canister filter pushes the "fins" at the top of the high chamber into a circle, much like how a blender works. The CO2 bubbles rise to the top of this dome (because they are air bubbles) where the ribs push apart and the bubbles are whirled up, broken up and mixed by the rotating ribs. There are holes in the bottom of the chamber so the CO2 bubbles never escape as they continue to rise. The CO2 bubbles stay and continue to swirl and mix with the water until the water absorbs the CO2 and only the water flows through the holes below while the CO2 bubbles continue to stay on top and mix until absorption. Simple but brilliant. Easy to install, simpler than other reactors. The only thing that could improve this is a small motor to manually rotate the fins away from the flow of your filter so it doesn't bind/slow down and break your flow. the CO2 bubbles down faster. I don't see any CO2 bubbles entering my tank and I put a lot of CO2 in my tank. I can't even count beats per second. One small issue: the CO2 air tube didn't fit snugly into the CO2 air tube on the reactor. I had to glue the CO2 hose to the hose on the reactor, otherwise the hose kept coming out when the CO2 was switched on. This is either because the cuff was too small or because my CO2 hose was stretched too wide/too slightly. Anyway, simple solution. I'm happy.
