Tunze 6045 on a Reef Keeper Lite

[WhoDey64]

Hi, I have been discussing the pros and cons of Vortechs vs Tunze in my local club forum here: http://www.reefcentral.com/forums/showthread.php?t=1780521

I think after seeing what some of the guys are doing with their Tunze I am convinced that is the way I want to go. Before I pull the trigger I would like to know how the 6045 would hold up being connected to my controller for pulsing on and off or if this would damage the pump.

Anything shorter than a 15 minute interval will damage the non controllable pumps(longer the better for long term reliability). Also keep in mind they do chatter at start-up.

A more equivalent pump for your comparison would be the 6055 which is a fully controllable DC pump. You also would be likely better served controlling them with a 7096 than the DA. The DA can only do off and on while the 7096 could ramp from varying speeds.

What size tank will these be going on?

36x20x20tall So a small footprint, 65ish gallons

Ok the 6055s would be the controllable pumps that would server you best from the Tunze line. Just making sure the larger were not needed is why I asked.

I agree with Shawn, the 6045 can only be cycled on and off every 15 minutes. I ran a 58 Oceanic with 2 6045 and it wasn't enough, it sounds like your tank will be a similar footprint. I would suggest either 2 6055 and a 7096 controller or seeing as by your avatar it looks like you are into soft corals the Nano wavebox and a single 6055 would be a great set up.

We have a 120 (4x2x2) DT and have been running with a nano wavebox and one 6045 for about 9 months. We recently added a piece of coral (porites with christmas tree worms) that introduced a bit less water movement in an area then we would have liked....along with wanting to increase intermittent flow in an area where we have gorgonians.

We run the Neptune Apex controller - so our fix was to add a 2nd 6045 into the mix, hoping to run it on an oscilating command from the controller. Not until I had it in the tank did I learn that these don't take kindly to being turned off and on.

For the same volume of water movement - which Tunze project should I be considering that will allow this flexibility?

Thanks!

The 6055 would be the best option, it will take being cycled off and on.
