Aeration and Oxygenation when using co2 in our aquariums.I have ordered 30 Neon Green ‘Rasbora’ Microdevario kubotai. On doing my research it says they like high oxygenated water.
Running a oase biomaster thermo 600 on a 170 litre aquarium with inline co2 diffuser. Planted with mostly Java trident and dwarf sag’ along salvinia. The outflow is contested to a spray bar pointing 50 degrees so the flow bounces off the opposite front glass then circulates along the substrate and then back up the tank give a distribution of co2.
From my understanding co2 reduces oxygen in the fish tank and then the plants exhale the oxygen at night! Adding oxygen via a bubbler when running co2 reduces the co2 performance- again please correct if I am wrong.
I have a good amount of surface movement - but not a massive amount as 1) I have floating plants and don’t want these blowing all around in the tank,
2) have the spray bar positioned under the water line - to reduce noise level!
With this in mind would I have enough oxygen available within the tank? Or would I be better changing or adding something. I do have a option of adding a oxygen diffuser (basically a mini bubbler that looks like a co2 diffuser- purchased from aquarium gardens) - powered with a air pump which could go on a timer or be used 24hr!
The temperature is at 23-24 so not a high temp - I understand the higher the temp the harder it is for water to maintain oxygen in the tank.
Other than the new additions, I already have 7 corydoras and 6 Otocinclus.
Any advise is appreciated - please correct me if I am wrong on any points!
