Powerhead Placement Help

Musicims · 12/25/2017, 08:06 PM

I know its another one of those threads

but I really need some suggestions. 75g standard size tank and 2 new Tunze 6105.

I cannot for the life of me get a perfect combo for flow going on. They are both turned all the way down @ the minimum 700gph. Figured these gave me some headroom if I ever wanted more plus they were a good deal used. This current setup is pretty close.

Don't mind the extra koralia on the left just part of the trials here.

The Tunze on the left rear pointing almost perfect diagonally slightly up to intersect some the the other, basically at the head on the right pointing at up and at the front glass. Move the left one its either too much movement on top and its crazy loud going into the overflow or they hit each other too hard and make a crazy sandstorm in the middle and whip my octo and flowerpot around too hard. Move the right one and it will hit the opposite glass too fast and clear all the sand in the two left corners within 30 minutes and create bubbles from hitting the glass that get sucked into the left pump that go micro. Tried the right one pointed at the front glass mounted further back near the return and practically blew the octo over coming down from the glass.

I'm very happy with where they are at here, not too much noise, minor sand movement, and lps is not in a hurricane but I fear there's not enough flow at the bottom and any minor change goes way overboard

. It has great flow upper 50% but not much below.

Side note I got a ReefKeeper Lite for Christmas so the APC module is on the way hoping I can maybe go wave mode and get some more flexibility here. I'm open to suggestions but I feel like I've put them just about everywhere possible. Thanks for reading!

I had two mp10 on the opposite sides aimed slightly up and at each other, with a korolla on the back wall on my 75.worked fine. In my 120 I have have two 6095 on the back wall pointing up and toward the side walls. I also have a maxspect gyre 250 on a side wall. That works great.

What always worked best for me is what Roger from Tunze suggested for my tanks

Both on the back wall as close to the corner as you can get midway vertically pointed at the front glass center. Then run one for about 15 seconds at 50 to 70 percent the other is on low 30 percent. After the 15 seconds the switch the percentages of the power heads.

Corals like flow but prefer a nice indirect flow with using the front glass it bounces off and will deliver a slightly pulsing flow (sorta like the ocean) and should work great keeping the tank happy...
