Airating tank with discus?
 
I read that discus likes a higher than average temperature and they also do not like too much water disturbance so I adjusted my tank accordingly. In general, the fish are much happier and livelier but I do find on very hot days that my discus sometimes gasp for air at the surface.

Would it make sense to put an airstone on a timer for a few hours every night to ensure sufficient oxygen in my water? My tank is planted so I am a bit worried of running an airstone too much for CO2 depletion but if it really becomes a problem I can look at CO2 injection as the fish are first priority...

Thank you
OJ

Do you run CO2 injection currently? Fish would be my top priority. Assuming your climate there at the moment is rather hot, then you really have to maximize the oxygen levels for the discus' sake.

I keep Discus (2) soon to be four at 84 degrees. They used to be in 55 gal. that was filtered with an emperor 400. It created considerable current but fish did not seem to mind. Often saw them at intake pecking at food bits held there during feedings. They are now in 80 gal. Filtered with same emperor 400 and an emperor 280 as well. In my view it provides some measure of exercise for the fish. The current is moderate and they exhibit no negative reactions. If your discus are gasping at surface of a morning at lights on ,it could be your plants are using up oxygen during the evening. Were it me I would add airstone and run it at night or increase the filtration which also provides oxygen. :)
