Moved the Korallias towards the surface
Within 1 hours O2 started to climb. The corals are looking better but PH is still low 7.6 but is expected to climb up.
Husband currently in her carport building sump, not allowed in the house until done 
She also purchased a CPR overflow since tank is not drilled. |
The plot thickens...!!
Wow...ya if I'm the jury, the jury is in, and the guilty part is oxygen starvation for sure! The glass lids wouldn't be a problem if you ran a skimmer, but from what I understand you don't have a skimmer, right? Then the powerheads not giving any surface agitation...poor combination.
pH is low because of elevated levels of CO2 in the water due to not being able to off-gas, and not enough O2 being injected into the tank. Simply adding an airstone will often increase pH. For more information on this subject read the pH heading in my guide on reef chemistry in my signature.
