I bought one of those "new" maxijets to pump water out of my mixing tank, I "transformed" it into a circulation pump just out of curiosity and I literally couldn't even get it to work right, its like a cheap toy, mine may have been bunk or I may have put it together wrong but I don't think so it works fine as a powerhead, if you want to go with less expensive pumps stick with koralia for circulation and maxijets for movingOf the ones I have used, I have found the Marineland Maxijets to be the most affordable, and versatile, especially for the cost, vs the others. About a year ago they started coming with the pieces to convert it to a circulation pump, that way you move even more water and it is not unidirectional. Great for lots of water movement without kicking up all your sand and disturbing fish and corals.
Happy reefing!
+1Vortechs. Yes they are expensive, and yes they work unbelievably well.
