I have my tank built in to the wall but will be moving it now. Right now i have a 30g tub that i premix it in and just open a valve and it dumps in the sump. Proble not the best way. I thought about some way to mix it with tank water then add back to the tank. How often do you do water changes?I dont do them near enough iam sure about once a month unless testing says otherwise . I no testing is to late shouldnt get that far. I am getting my *** in gear and doing maitnace like i should now. But i will be moving it to a stand so will not have room for all this just woundering what you guys do?
