TUNZE powerheads
 

Wanting to replace my maxijets with TUNZE powerheads, wondering which one and how many I should get for my 90g reef w/25g sump.

I am leaning towards the Tunze 6060.

What do you all think???

Thanks

I have the 6100 and the 6080 in my 75, and that's really moving some water. You could probably go with 2 6060 pumps, depending on what you have in the tank, size of corals and type of sand on the bottom.

to elaborate on Brad's last statemen, it really depends if
1) you have sand in your tank or is it bare bottom?

2) are you keeping softies, lps, sps?

a 6060 in the tank with sand will move a lot of the sand around until they settle wherever the flow is less. softies and lps might not appreciate that type of flow in a 90
but if you have a bare bottom and growing acros, go wild with the 6100 and 6080s, they will keep the crap off the bottom for your skimmer to export.

I have about 1-2 inches of sand in my tank but just in front, behind my rock is bare.

I only have LPS, clams, shrooms, zoos that sort of thing...no fuzzy sticks for now.

So a 6060 placed at the top of tank would still move the sand around???

Thanks for the replies

I had sand in the 120g (4" at least) and ran two 6110 tunze's in there. Sand moved for the first day only, after that it settled down.

Currently have 3 6110's in the 90g, will be adding a 4th soon :)

Course, I like fuzzy sticks (tm).

My 24" tall tank is using a 6100 with fine sand. The sand is not flying around. One could also set the pump at a lower flow rate if needed.

if you keep the 6060's to the top it will be fine. I had two in my 3 foot 94 gal and then never moved the sand but you have to get them positioned just right.

I guess that since mine is only 18" deep, and I put the streams in the rear corners pointing at the opposite front corners is the reason I can't use sand. It's all in the where you put them I suppose.

I had one 6060 in my 120 gallon mixed reef, LPS and softies/shrooms.

I ditched the 6060 because it created too much current. Soft corals would be blown over sideways. Frags I tried to glue in place would get blown around.

I switched to a Seio but it was too much flow as well, now I just use my return pump for flow and things are fine.

IMO the streams are good for SPS probably but too much for a mixed reef.

I find that my zoos and GSP are fine with the current, and I'll be adding a large hammer next week. I suppose if you had a large leather inthe direct path, it sure wouldn't be happy, but again, I think it comes down to placement in individual tanks. I have surf type movement in my tank, but still have some zones with almost no movement.
