Let me say I am a beginner to the CA Reactor. It is proving a little harder for me to get dialed in then I thought. My drip rate was slow and got clogged up(I think when I moved it and stirred it up).... so had to start dialing it in again, had my CO2 adjustment nob get bumped, blasting CO2, had to start dialin in again, Had a leak in a connector and had to refil the tank. Also it is hard with my set up to make small ajustments ie change the bubble count from 1 bubble to 1 1/2..... I think it will be great as soon as I can get it adjusted better... But I sure like the looks of the comas frag tank with the dosing pumps!! I am interested in hearing from others.
