Yea, apologies should have been clearer about that.Hmm when plugged into your skimmer the ORP and Ph were consistent?
I’d guess you just disturbed something in the sump adding the air stone and the ORP will slowly climb back to normal within a day. That probe can take a dive at the slightest disturbance and takes forever to get back to normal.Yea, apologies should have been clearer about that.
My advice? 30% water change and take all the extra equipment off. Get back to basics and add one thing at a time. Start with a pump, heater and skimmer, nothing else. Let that go for 3 days, and then do another water change. Get some stability back into the system.Most of my corals are in decline…….. I have zero idea what this triggered.
There aren’t any measurable instabilities outside of this ORP drop though which everyone seems to feel is an irrelevant factor. Alk and cal haven’t deviated more than .2 dkh and 20 ppm respectively.My advice? 30% water change and take all the extra equipment off. Get back to basics and add one thing at a time.
