not here either, but maybe a frag tank. I don't want to pummel my frags, just curious

personally i preffer function to fashion any day but my main issue with these is that they mount by suction cups and i will never use a PH that is secured by a few suction cups...

i have always been fond of the koralias as they have a very sturdy magnet holding them in place... oh and the vortecs..

I've used them before. Algae Free Sure Flow Upgrade Kit gives considerably more flow from the powerhead.

Maxi Jet 400 = 1300 gph with the kit
MJ 600 = 1400 gph "
MJ 900 = 1550 gph "
MJ 1200 = 1600 gph "
MJ 1200 with large impeller = 2100 gph

You can also get the Algae Free Sure Grip magnet holder which replaces the suction cups and works well.

My biggest compl;aint with them is they are large and ugly and the flow is concentrated and should not be placed too close to corals.

I actually used a mj in one of my old tanks, I moded the mount to add magnets. Agree though, no suction cups
