I've been using seachem products for a long time now and my tank has been doing well. My concern is that the alk. level fluctuates between 2.5 and 4. I don't want to set up a dosing system, but I was wondering if anybody had used the B-Ionic additive system, and if so is it a good product to consider? I don't mind if I have to add it everyday, as long as the water conditions stay more consistent. Are there any other products that do the same thing? thanks for any advice.
