I highly recommend the Maxi Jet PH's. I have had them all and I like these the best by far. They will stand up to a wavemaker very well. They will not burn up if they run dry. You can even run them external...although I'm not sure I'd trust them not to leak in the long run if used in this manner.
If you have a 4" DSB
and 45lbs LR
, I would strongly recommend not using the Bio Wheel. I think Bio Wheels are hard to beat for FW
use, but I have known people who used them on SW
and they always had a nitrate problem. Your LR
should take care of bio filtration with no problem.
