Thank you for the reply.
I know the ph goes low at night but this was way to low, no to mention it was on the low side last night. It is back to normal now.. After I post this, I aimed a powerhead up a little.. I had messed with it a couple days ago and wasn't getting as much surface agitation so I'm assuming that was the problem. Dkh
was a little low but not bad.. Still doing a water change as soon as it reaches temp..
I think in the end surface agitation was my problem, I will monitor the ph and dkh
the next few days
