Air Stones & pump size, what do you like?

Right now I'm using the 3' flexible tube type 'stone', but they are getting clogged on a weekly basis.

Is there something better?

Do I need to keep a 2nd set and swap them weekly?

I've got 4 3' tubes on a SDA530 sunleaves air pump (1 per tray, 4 trays). It does produce a 'fizz' from each stone, but I really want it to bubble and splash.

Any suggestions?

Thanks in Advance

The Grow:
-I'm using rockwool in hydroton with 5" net baskits in a 10 gal Rubber Maid wick system.
-(I think the wick system does great as far as growth and is less expensive than Ebb and Flow.)
--(Of course I am a non-qual-dink-puke-newbie, what the hell do i know)
-FloraNova nutes, ph is 5.8, ppm is 1500
-24 plants (6 per 2 week phase) under 2x400 HPS and 1x400 MH
-6 active mothers with 5 new mothers coming along (at different ages) under 4x4' floros and some CFLs.

1 watt per gallon. I use 5'' air disks; they don't get clogged anywhere near as much at those "tube" types.

I have to agree with going for air disks or long air stones because the tube bubblers just dont cut it and are not as good.

I use two 12 inch airstones with a four watt dual outlet pump for my 3 gallon rez. It works real well and there are a lot of bubbles. The airstones haven't clogged with the nutrients I add which is great. I plan on using it for a DWC in the next couple months

Thanks for the info!
