    Is it feasible to add kalkwasser to the saltwater reservoir?

    Since my calcium reactor cant seem to keep up with my alkalinity needs, would it be feasible to dump some kalk into my saltwater container? I've implemented automatic water change of about 7500ml/day. Would there be issues like clogging the lines, burning up my DOS, screwing up the chemistry?

    Could Teflon Tape Prevent Skimming

    Two weeks ago I replaced a broken needle wheel shaft on my skimmer. While I had the skimmer taken apart, I put Teflon tape on the venturis’s threads to prevent micro bubble escape. So now, loads of bubbles but no skimmate. Could the tape be releasing compounds that are preventing foam production??

    Odd drop in Alkalinity

    Why am I seeing such a low measure of Alk? I measured it at 5.6 today. The Alk was struggling to stay over 7 the last 2-3 weeks. Last year, I had to watch things or the Alk would jump over 10! I'm running a calcium reactor AND a Kalk reactor so this really made me scratch my head. I've...
