Gully Washer,
Are they rated for continuous use? That is, can they generate oxygen on a continuous basis or do they need to stop periodically? No clue so that is why I'm asking.
And just to be clear the back up system with the solenoid is not an original idea of mine. I found it in a couple of texts but of course the information was not detailed.
5 to 10 lpm is lower than what I run in my tanks (I run about 20 to 30 lpm from my center diffuser, but it could be enough to prevent a fish kill if the tank is deep enough to allow enough contact time.
