Hi Guys,
I have been thinking about adding a closed loop to my tank for some time now, but I am wandering how to go about setting it up.Firstly I have a Resun PG 18 000 pump ( 18 000 L/hour) and a Oceans Motions 4 way wave maker. My concern is about weather to drill the back glass or go over the 100 mm bracing at the top of the tank.I was also thinking of adding 2 more outlets from the same pump back into the tank and in so doing I will have 6 outlets. If I was to drill the tank then would it be advisible to remove the abs sheeting from the back glass and paint the tank instead?
Cheers
Shane

I am personally looking at setup my Polario externally and the easiest way is over the top, rather than drilling. Also I can modify flow outlets if required, where drilling is pretty permanent.

Really easy, correct size PVC piping either side, over the top of the tank and down the corners with elbows etc, and you done.

Thanks guys,
I am not able to see any pictures that are uploaded on photo bucket.
I have decided to go over the bracing as I am weary of drilling my tank.
Is using a 18 oo l/hour pump through 4 outlets too much or the more the better?
I am planning on 6 outlets 4 from the oceans motions and 2 from the discharge pipe straight into the tank. All will have ball valves to control the flow.

Was just joking around, did not really upload pics Shane, but I understand what you say

What diameter pipe you using, and yes, you can go with a stronger pump as you have a lot of outlets. Only thing is, your last outlets will have weaker flow, unless you extend the pipe and add another pump on the other side, so basically the 02 pumps will blow "against" each other thru the same pipe

Awesome advice Sean! I too have a sort of a CLS in my tank, that supplies water flow BEHIND my live rock, as to ensure no hidden detritus....And I have 2 pumps pumping into a 25mm clear flexi-pipe, with multiple outlets....(I used "t"-s as outlets...)

Hi,
I was planning on using 32 mm piping from the Oceans motions into the tank and possiblly 20 mm piping for the other outlets. I was thinking about extending these 2 outlets deeper into the tank and ending off with a t piece with 2 45' bends on either side of it.
cheers
