Since my CYA is between 30 & 40, I have been keeping my target Chlorine at 5. BUT then it seems to need chlorine every other day, chlorine will go down till about a 3 on the second day. Is there any problem doing it this way? I check the chlorine ever day, so I am not going lower. So just wanted to make sure that it is ok to "aim high" with the chlorine.
