So I use a kalk stirrer and have been using it for a year it’s worked amazing but as of recent it’s had two instances of dumping tons of water into my display tank, my kalk PH is 11.4 and I use my kalk reactor at night to maintain kalk at about 8.5 I don’t understand why it would dump all that kalk reactor water and have no effect on the ph of my display tank? I even measured the ph of my tank with a separate ph monitor and got back the same results. I’m just frustrated and confused any advice would be great
