![]() I went to AA today and Dan and Nicky were a huge help.
Test results were Salinity 1.024 PH 7.6 / 7.8 KH 11 Calcium 440 Am 0.0 Nitrite .5 Nitrate 15 O2 wait for it 0 ZERO Zilch Nada Nothing |

![]() So dissolved oxygen was 0 mg/L? Am I reading that correct?

![]() how the heck can disolved O2 be 0? Should so something, I mean a little water is allways in contact with the air, even with pumps off

![]() Putting tank water into a container, travelling with it for a time, then testing it later on is absolutely not an accurate measurement of your tank's dissolved oxygen level. You have to take your tank water out, and test it within a few minutes of removing it from the tank in order to get an accurate test as shaking the water a bit will increase the dissolved oxygen content, and letting it sit will lower the dissolved oxygen content, even in a sealed container. Don't consider that test your be all end all, it has very little bearing. I am surprised the employees at AA didn't know that or failed to express it to you. It's kind of silly they would even test customer's O2 levels from the store since their readings would never be accurate.

![]() Just a little surprised That after all the water changes you did after the crash, that your O2 levels would still be so low...

![]() I agree with Myka, and that is probably why your test sample read 0 for O2 at the store after all the water changes.
But after thinking about it last night I agree that the cause of the crash was oxygen starvation

![]() Actually Dan and Nicky suggested the O2 could be depleted. She purchased a test kit, went home,tested the water.....VOILA !!!!
O2 = 0.00 Opened the lid ( tank has glass lids) Added a couple of airstones and powerhead 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.

![]() I (and I'm sure others as well ) didn't know that there are glass lids on this tank, The lids as well as no surface skimming due to the canister filter is why there is no oxygen exchange at the water surface..... THE Glass lids have to go !
The PH will rise as the O2 levels go up and the CO2 levels go down ( CO2 drives PH down, same principle as a calcium reactor)
