Hi everyone. Tank just cycled and pH dropped to 7.6 how to rise it?
Only 1 fish in tank and no corals yet
Heres today parameters
Btw I changed 10% water today
Crack a window open and put an air stone is. My guess as to why the pH dropped is because of a bacterial bloom depleting O from the water. Is your tank ckoudy?
This might help...also our hobby test kits aren't that accurate and prone to error so your measurements may be off

Aquarium pH Distilled
I just wanted to share my understanding of reef pH which is mostly based on: Low pH: Causes and Cures by Randy Holmes-Farley - Reefkeeping.com Many would agree that reef tanks can be successful with pH between 7.8 – 8.5 NBS and daily swings as great as 0.5 NBS. Natural pH levels in our ocean...

Are you using a low alk salt mix? Distilled water and RODI have low pH values, but when mixed with an alk between 8-12 the pH falls into ideal ranges. 7.6 isn’t something to lose your mind about, but it’s also unusually low for a reef tank. Calcium carbonates will help to raise it a bit. It doesn’t have to be above 8, mine is usually 7.8-7.9, but 7.6 is oddly low. Remember that the pH scale is logarithmic, so it 7.6 is 40 times more acidic than 8.0 so if it gets any lower I would be worried. I would try the air stone and window first because it might be co2 saturation.
