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

Super cheap, works well for "in tank" or part tank solutions, I'm a little leaky in suggesting it for external use, obviously you could put it all closed but out of the box, slightly siliconized flow a little. There was a bit of burr from the plastic mold that had to be scraped off in order for the tube to fit snugly, but given the very reasonable price, expect an extra minute or two with a razor blade. I run a few bubbles per second, I also increased it a bit more and it still works fine as there are no micro bubbles in the water outlet tube. My main pump is too big for it, so I bought a super cheap 800 l/h pump. With a few small zippers it fits easily into my 1/2" pipe. There are a few corners but they don't seal well, you have to secure them with silicone. The bottom is removable for cleaning but it leaks, me could cover it with silicone but no need as I have it in the pan.
