    Tweaking DIY Chlorine feeder

    DIY feeder in another thread. It feeds 32 oz. during 4.5 hour pump cycle (2PM-6:30PM), is this normal (CYA 45):

    2PM: FC = 4.0, CC = 0
    6:30PM: FC = 5.0, CC = .75

    Same each day for 3 days, although CC was .25-.5 at 2PM 2 of the days. I'm happy FC isn't going below 4, but wonder if "random" CC is normal.

    Yes, you should expect to see CCs popping up, your lucky you regularly have CCs of zero, some pools and almost all indoor pools never achieve this

    Re: Tweaking DIY Chlorine feeder

    Thanks. So far very happy with my Clorox "feeder". Down exactly 6 quarts in 6 days, readings just keep going from 4.0 to 5.0-5.5 each day. Only thing I have to do is add acid maybe every 3rd day to keep pH in check. I seldom get those CC=0 readings, normally is probably .25-.5. No worries unless my needle valve gets plugged and I don't notice it for a few days because I get too over confident in the automated system (forgetting to check FC). I'm thinking checking FC and pH with test strips is probably a good fast way to go daily, and using the Test kit maybe weekly.

    Ouch, I think most peeps here would rather you ditch your test strips and test with your kit exclusively, test strips are notoriously unreliable and will likely cause you confusion when they do not agree with your test kit results

    Well, I've been testing with kit AND test strips for a few days, and I find as long as FC is below 5, the test strips are close. pH seems to read lower than the kit. I figure if I use the kit once a week I'll be fine. I only really want to use the strips to make sure I have some FC, if it shows very low, I'd retest with the kit.

    Fraud we will need to agree to disagree then, you will likely not find anyone that would endorse the use of strips cept for testing borates on this forum.

    I don't disagree, I just have 50 strips from the previous owner, so I thought I'd use them up. I doubt if I'd pay money for them.
