So I broke my inlet pipe on HOB fuge/skimmer last friday and had to take it off line temporarily. The first day everything seemed fine then after that I noticed every closing up and my sps were starting bleach. We'll I did all the testing and besides my alk being a tad low, my ammonia spiked. Would bringing a HOB offline cause such a reaction. Could it be the lack of oxygenation the tank normally gets? I feed my fish every other day so I doubt over feeding is the problem. Seems a little coincidental.
