Small Powerhead

[slapshot]

Tunze is awesome, but to pay nearly double the price for a powerhead that is going to be from the sounds of it tucked behind the rockwork anyways does a slightly bigger sized koralia make much difference? Also the possible start and reverse issues only come into play when you have them on a timer or turn them on and off frequently.... most can be solved FME with a dab of glue on the rubber bump stop as well I have been using my 3 1400's for over 2 years now, and a 750 for about a year, all but the 750 have been on a timer the entire time as well. Only time I have had issues were when the rubber stop on the front cover came out and jammed the propeller, glued them all in place and haven't had a problem since.

As far as heat, I ran my 180 at 75.5 degrees w/o issue w/o a chiller for 2 years, hottest it ever got to was 77.1 and that was on a day that was over 80 and we didn't run the a/c.

For the purpose of the pump I would go with a koralia 550-750 atleast and put the extra 20-30 towards something cooler lol

This is a case of you get what you pay for though. I would submit the Tunze out performs the cheaper ones by pushing the water farther.

Yeah my tunze 6060 (1600gph) will kill my evolution 1400's for distance.... but the compared initial cost it kills it as well... and for a 55g do you really need to be able to push the water 6' instead of 3-4'? lol

True enough, but my koralias 6 won't push past 2 feet.
