| Post subject: | Keeping water oxygenated |
I have a 80L FT in my house and am currently hoping to keep it aerated using a spray bar and a return loop from my pump. There is lots of water agitation, but I do not know how much dissolved oxygen that really translates to...I haven't a DO kit. Is a mechanical aerator always necessary or can water agitation do the trick in smaller tanks? I can't find much info on DO requirements. Thanks! |

How much aeration you need is really dependent on how heavily you've stocked the tank and what kind of fish you have. In an outdoor system the temperature would play a more important role as well. If you haven't stocked heavily you'll probably be fine with what you have. For Trout, keep Dissolved Oxygen above 5 mg/L. Many other fish can handle 3 mg/L but below this growth slows. I'd probably just shoot for the 5 mg/L level anyway. The few times I've measured D.O. it's been at least 7 mg/L and this is without additional aeration (just mixing from circulating the water). I usually have light fish loads. The warmer the temp the less oxygen the water can hold. |
