ok so i have my plan on my skimmer have any of you used a gravity fed Beckett foaming fountain nozzle i have a what looks like a good idea when he puts it on it does a very good job from what he says and u can see a ton of bubbles, but he is also using a pump but said it can be done with gravity so i think i might try that out first just to see what its like and how it works if i can get away with out the pump $50 saved. ill post up the picture of the plan and a link for anyone else wanting to make there own. he also has some very good money saving ideas on making your own float switches.
