100L LPS tank, light bioload.
I leave for 23 days on Tuesday. a faulty Hanna Alk reagent and me overdosing All-for-Reef resulted in a dKH of 12 this morning.
For the last month I have been dialing up my All-For-Reef dose trying to raise Alk from what I thought was high 6.x to about 8-8.5 dKH. I missed some early indications that my Hanna checker was wrong because I was not getting the Alk response I anticipated.
I do not know what my alkalinity was 1 month ago when I started increasing dose of AFR. That bad bottle of reagent has been in use for a while. I normally dose 300 ml of Kalk per night and previously a very small 1ml/day AFR. It’s a 100L tank. My tank is fairly low demand.
I dosed 5ml of AFR for a few weeks and on wednesday I increased the dose 8.3ml, thinking I had found the Alk consumption and was trying to match it.
My Hanna reagent ran out this morning, Alk was 7.3 dKH on the last test this morning. I opened and new reagent and tested again. 12.0 dKH. I verified with a Red Sea Alk test. Came in about 12.0.
So, I am mixing some water to do a water change, turned off AFR dosing pump, but I am unsure what else to do. I leave town Tuesday. I typically leave my tank for a month at a time and my daughter just feeds the fish. I could teach her how test alk.
I am sure other elements are high too, because it was all-for-reef. I haven’t bothered checking.
Yes, corals looks unhappy but not dying.
Advice??
Thank you.
