Modified Reactor 1000 and microbubbles
I am completing a new 110 gallon in-wall show tank. I have plumbed a modified Aquamedic Reactor 1000 inline in the return plumbing. It has been modified by increasing the inputs and outputs to 3/4" hard PVC. I am moving about 450 gph through the reactor which is then split into 2 returns to the tank, which I believe is fairly high flow compared to what many forum members use. My problem is than most of the CO2 bubbles exit the reactor immediately without being disolved, leading to microbubbles in the tank (which I understand is good for plants, but I find it unsightly), presumably from the high flow and the location of the CO2 entry near the bottom of the reactor. My question is, what are the opinions of taking the black entry tube out and trimming it, so the CO2 is entering higher in the reactor? I presume this will help, but would like some feedback before I chop up the reactor.
