water movement

[bluerage]

hi all , im about to set up a new system 5ftx2x2 and was wondering what would be a good lph water movement to have ?
im going to have a mixed tank with few fish and loads of inverts.

You to aim for around a 30x turn over rate. I would just get 2 seio 1100s or maybe 3 and that would be good. Or you could get a couple maxi-jet 1200's.

Are you runing a sump and a return pump?

hi

hi

yeah will be running a sump and return , will be a closed loop job

 

[Andrew]

How many gph will your return pump be?

 

[bluerage]

well im going to run two in case one should go and from what i been told it will be about 7000 lph , i cant check cos all the bits ive acumalated are in the shop still.

 

[Andrew]

Well there are 3.7854118 liters in a gallon so that would be 1849.204344035665995158048629018 gallons.

Thats already a good pretty amount of flow. You might not need powerheads with that large of a return pump.

I'm still wondering how I'm going to do this with my 75g. Would 2 Sieo 1100s on an wavetimer (aquacontroller jr.) be sufficient for my mainly SPS tank? Or would it be more of a natural flow to run a CL with an Iwaki MD70RLT with about 5-6 outlets?

EDIT: Just remembered, Seios cannot be hooked up to a wavetimer, correct?

 

[Andrew]

I heard you don't want to run seios on wavemakers but yes, two seio 1100s would be good for a 75 thats an SPS reef. Im running 2- 620's on my 75 thats going to be a mixed reed and I wish I would have gotten 820's or 1100's.

Yeah, if you run Seio's on a wavetimer, that turns them on and off, the hard starts will eventually crack the magnet drive in the pump.

 

[REV]

You can ask TAAM, Inc. and they will tell you that the Seios are not designed for a wavemaker or timer setup. Don't frustrate yourself with them unless you plan to leave running constantly. Have you checked out the Wave2k? (wave2k.com) Mine shipped today... I should be setting it up this weekend!

 

[laszlo]

Yea, I see that they shouldn't be run on a wavemaker. I was thinking about the wave2k a while ago, but then I figured any type of wave maker and an overflow box won't mix.

Well, it is decided that I will be running 2 Seio 1100s.
