I was wondering if any one else is using these type of pumps?

I have the Ario 4 in my 36 gallon and the Ario 1 in my 10 gallon. They work great with out the noisy air pump and the air stone. I recomend any one that gives their fish additional oxygen to look into it. The Ario 4 has worked great so far, but the Ario 1 seems to plug up frequently prolly from the live plants and brine shrimp, so I would not get that small model again, they all have regualting valves on them to control air flow too. BTW my girl friend paid like $30 for the Ario 1 at Petco, but they are much less money here.
