So yesterday I went out to get my first frag, a lovely GSP. When I left my house I looked at my parameters and other than a little high Nitrites I was in the zone for ok frag adoption. By the time I got home and put the frag in I waited a little while (about an hour) and the frag was not opening. I checked my parameters and my PH was 7.65 and dropping on my Apex. It was late in the evening so I couldnt run out to get some kalk at my LFS. I went to bed hoping it wouldn't drop any more overnight (knowing it would but hoping it was not too bad). I woke up at 1am and checked, it was 7.48 and dropping. I panicked and ran downstairs and did a 25% water change on my 60+20 tank. The PH gently rose back up to 7.7 (I use Meersaltz Pro Reef). Over the next 2 hours it dropped fast, down to 7.5. I ran a hose out from my skimmer out of my window. It did nothing. All I could do is wait until morning. I got some kalk and set up my Osmolator 3 ATO through a spare filter canister (sans filter) filled with Kalk. Once the ATO was done topping off I manually added a little bit to my sump every 20-45 minutes. I am finally at 8.3 but it took 5 hours or so.
Questions:
What caused this to drop so insanely fast in the first place? I do have pets other than my kids so I assume that may have added to the CO2
Raising up almost 1 point in 5 hours is that too fast?
That big spike in the middle of the lows is me recalibrating my PH sensor. I have 2 other sensors and they were all low but some a bit higher than Apex so I thought I should check it for calibration.
Other Parameters:
Salinity 1.025
ORP 177mv
Ammonia: 0.00 (Salifert)
DKH Now 9.0; During low 8.0 (Hanna)
Temp 78
Water change water is from 7 stage RODI
Thanks!
