Adding second return pump

[Mekaeel]

howzit guys.was looking at a bigger water turnover in my tank.my return at the moment is a 6000lph return pump.im planning on adding a second return pump which is lying around.the pump is a king4 4800lph.it will be appreciated for advice on the direcion of the flow using the second pump (plumbing again sheesh).ive added a diagram to show you guys what the setup is like at the moment.thaks crew

I would put it in the middle of the tank blowing slightly off centre towards the left and right front corners of the tank.

 

[Kanga]

I would run it this way with a SCWD to get nice random flow, however increasing th flow over your DSB might not be the best thing to do

 

[viper357]

ah Kanga, great minds think alike, even though your arrows are a bit cockeye

 

[Mekaeel]

was also thinking along those lines.sounds cool guys.the SCWD obviously will increase flow,correct?

 

[viper357]

No, the SCWD will actually decrease the flow slightly. It will alternate the flow between left and right.

 

[Kanga]

was also thinking along those lines.sounds cool guys.the SCWD obviously will increase flow,correct?

No actually decreases you flow slightly.

Mhh Viper the cockeyed arrows are to, eer uhm , add to the randomness of the flow?

 

[Mekaeel]

i guess that will defniatly be better than a standard T piece

 

[AndreT]

Mekaeel, yes, Sqwds are awesome. I use one myself and have used on on a previous setup. There are a maximum flow you can push through the thing though.

 

[Mekaeel]

im sure once you take into consideration the height and the bends of the pipework it obviously will really decrease the flow of the water comming out

 

[Smithers]

What I did to increase my water flow was to upgrade the pipe I was using. What size pipe do you have currently ?
I went from 20mm to 25mm and the difference was huge and that is only on a 2800lph pump.

 

[Mekaeel]

howzit gavin.i am using 25mm

 

[Smithers]

You should get something like the OR6000 and use 32 mm Pipe with a T piece on it. Seems like a lot of water to go through the sump though. Why not add some Big 'ol Seio's or Tunze's to your tank if you want to get more water flow.

 

[Mekaeel]

i do have alot of flow in the tank and also just added another seio m1500.just anted the actuall turnover ie.water from tank to sump and back faster

 

[Kanga]

mekeaal, i dont think its good for water too flow too quick over ur dsb.

Speak to milleporra (andrew) he would be the right guy to ask

also, i dont think you should have more water going through your sump than your skimmer can handle

imho

 

[Smithers]

Get a 12000 LPH pump from a koi shop. Will make the turnover much quicker

 

[Mekaeel]

ok in the display,4*seiom820,1*m1500,2*lifetech 2500lph pumps & 2 lifetech 1000lph oh yes and one little king1

 

[Kanga]

below see what mille said about how a dsb works, it just seems that too much flow cant be good over it.

Water moves through the sand via attraction. The water surface is negatively charged while the bulk of the tanks water is mostly positively charged, the sand bed is again negatively charged, therefore water defuses through the sand as positive charges are attracted to negative charges

did u get the resun wavemaker yet ??? that will help flow tremendously
