Too much oxygen quarantine tank?

[ibrat82]

Hi guys

Is there such thing as too much oxygen in a quarantine tank?

Currently I have 2 juvenile Bartlett Anthias and a juvenile yellow tang in a 20 gallon long and all are doing fine. However I'm overdoing it with oxygen. Currently in the tank I have a nano internal skimmer, small air stone, and air sponge filter. All giving oxygen.

Is this too much for the fish? Should I tone it down?

O2 saturation (at 100%) is a good thing; cannot overdo it. Air stone doesn't actually 'give' oxygen; it promotes water movement which brings stale water into contact with the air. Probably unnecessary if you are using an air sponge filter (which does the same thing). May want to add some flow though, particularly for anthias.

The key to remember is that there is more to your dissolved O2 saturation than just how many air stone and water churning things you have running. The major factor is water temperature followed by salinity. Higher temps and higher salinity can hold less dissolved O2 than colder fresher water sources. I am not saying you should freeze your QT tank with near fresh water, but be aware that those two factors limit your max O2 no matter what you try to do. Without a meter it is probably best to just add as many air exchange sources as you reasonably can, just to be safe. I just would not turn it into a Jacuzzi chasing O2 saturation

As long as everyone is looking healthy and not annoyed with the bubbles you should be fine with the fish in there. If you qt corals you may want to tone it down and corals don't tent to like bubbles on them
