Hello everyone, I have a 40 gal (total) AIO that has been running for around 6 months, I transferred it from a smaller tank with existing media, water, rocks, etc.
We have had low pH since the beginning but we didn't want to chase numbers. (averaging 7.9-8.0). The other parameters are stabilizing but pH has started to drop drastically (as low as 7.5 averaging 7.7). My corals are starting to die and I out of ideas of the cause that's causing it.
Last parameters check (none others checked):
Temperature: 77.3 F
Salinity: 1.023 SG
pH: 7.9
Ammonia: 0.25 (always this result, using API)
Nitrite: 0
Nitrate: 15
Calcium: 460 (dosed after this)
Phosphate: 0
Alkalinity: 10
Magnesium: 1230
Things I have tried:
Buffer in RO top off water to keep at 8.3 and above
Buffer in tank to raise (it drops quickly)
CO2 scrubber
Leaving a near by window brings it up to 8.1-8.2
Added gyro/wave maker to increase flow and surface agitation (also have an additional flow)
Is there anything else I can do or what may be causing this to happen? Thanks for any insight you may have.
