Water flow

digital-audiophile · #1 10-23-2007, 05:41 PM

In my 90, I get a little bit of flow though mostly aeration from the return line on my sump, I have to Hydor Koralia 4's on both sides of the tank for flow. I am thinking about adding a Koralia 3 in the middle of the back wall to add a little more mixed flow. I'm not keeping SPS right now so the flow is not as vital and with my sand bed it is a challenge to adjust the flow so it doesn't stir it up too much.

in my 370G I have a hammer head return split into 3. 2 wavey seas and regular lockline on the 3rd. The hammer head also feeds my chiller that returns to the sump and a 30G frag tank that also returns to the sump.
I use a Ocean Motion 4way on a closed loop drived also by another hammer head pump. There are 12 outputs to the closed loop that have on off functions depending on the OM 4way

In my 120 (48x24x24) there is a tunze wavebox, two 6100 and a 6000 tunze stream.

24g nano - mag 7 return on a SWCD, and a hydor koralia 1. SPS & clam dominated

28g nano - Snapper (2400gph), on a Calfo manifold. Will be SPS & clam dominated.

145g BB mixed reef. Dart (3600gph) on a CL with OM 4 way, plus a Iwaki MD-70RLT on return (with head I'm still flowing ~1000gph).

How tank is laid out (returns and rock) think I'm about max for flow as getting difficult to find lower flow areas for stuff like LPS and clams.

On my 210g LPS dominated reef, I have a Hydor Koralia4 (1200gph), 2 @ Tunze Nanostream 6045s (2x1100 gph), a Mag7 return split 2 ways (500 gph), and a Sedra 9000 return (700 gph). That's approximately 4600 gph flow after head loss, and all the flow is higher up in my tank.

On my 135 mixed reef (72x24x20) I have one Tunze 6000 on a single controller (1850 gph) plus an Eheim 1260 return split three ways (one looped back into the sump (~400 gph back into the tank).

That's not all that much but I have less live rock than most others have in tanks of this size and the rock is arranged to allow for Gyre-type flow - think of a racetrack with the water circling around the track and the rocks in the middle infield. So I've been able to get away with less gph and powerheads.

tank size 56 gal 36x18x20.
mag 12 return.
mag 18 closed loop on a scwd
total flow around 2360.

oops, I forgot to answer the whole question...for the first one I would love more flow, but none on the second one.
