Hi all. So due to my pH woes I think I'm going to start dosing kalk. I'm going to get a small container for it, get the brs 1.1ml pump, and hook it up to my apex. I'm going to have the pH limit set but my question is, is any other failsafes I can put into the apex to make sure it doesn't overdose? I'm going to use a relatively small dosing container just in case it does all get dosed at once but I'd like more failsafes if possible. Thanks guys!
