oxygenate the solution
 

Hi Ron. Got a question or (2) for you. First I've read on several posts here that you should run your pump 24/7 to save wear and tear on it, but then it is also said to run the pump on x/off x. So which is it?

Also found a site that was saying that you could take 1/2 the output from the pump and have it spray back into the reservoir directly and that this action alone would oxygenate the solution enough for health plants. Does this sound right?

I run my pumps 24 hours because it's less hassle and my plants don't seem to mind the extra watering when it's dark.

Yes that is an excellent way to add oxygen to your reservoir and at the same time cut down on the flow to your garden. I used to poke holes in the hose just above the pump to relieve the flow to the garden. Ron
