I recently raised the temp (to 85 f) in my fish/reef tank for various reasons (partly to help kill ich). I know that warm water holds less oxygen that cold water so I needed to make some adjustments. I have four powerheads and two Emperor 400's and a skimmer (total of about 2200 gph). The water agitation was decent, but pointed two of the powerheads up to get a better gas exchange. The powerheads I have have optional air intake valves that I know (if used) could raise the surface agitation and therefor the gas exchange. I have heard that the air bubbles are bad for fish in salt (good for fresh) but others have said that it doesn't matter... Aside from being unsightly and hard to see inside the tank is it bad? I wouldn't mind asthetic changes for a short time if it means better gas exchange whilst the temp is up...but I certainly don't want to make the situation worse for the fish.
