changing existing CL??????
 

ok i have a closed loop already with a 1.5" bulkhead drain and a 3/4 inch bulkhead return and the pump is capable of around 3200 GPH well the 3/4" bulkhead under pressure is only good for around 1800 GPH so i used loc line Ys and have that 3/4 line split for 4 differnet loc lines and its in the middle of my tank with 2 rock arches on the sides and well its ****ing me off now its an eye sore..

so what i was thinking was if i ran a single 1.5" up the back and tee'd off to 4 or 5 3/4 inch lines into tank either adjusted by valves or an OM 4 way that would be ok right?

the 3/4" bulkhead is threaded so i can unthread the loc lines and thread in a cap for the 2 days it will take to plumb and set and the intake also has a ball valve do i can do this without driaining any tank water.

now i wont have any flood issues because the lines will come over the back of the tank so they will be higher than the water level in the tank in case of a power outage.

i will also leave a single loc line the the existing hole in the back of the tank but short and barely noticeable.

the sheer amount of flow isnt my issue its just id rather have slower flow coming from 10 different spots and angles as opposed to massive flow from a few spots....................

is the OM 4 way worth the 400 bux they cost?

i have a canopy so any piping over the back will also be concealed

I have an OM 4way and love it.

Same here love mine too.

Liking my 4 way as well.

Take a look on OM's WaterPix forum, few over the top setups there.

I just picked up an OM 4 way from another user on here, and I love it. You can set up many flow patterns with the various drum version so you're limitless really on what you can do. It took me 4 months of waiting for one to come up for sale on here, but I did get a heck of a deal on it...it pays to wait a while if you're looking for a deal. I've also ordered parts from Paul & Cass, and their service is top notch

If all you have for your returns is 3/4" you could use a slightly less expensive super squirt however you will lose some flow if you do. If money is a real issue you may be able to pick either one up used if you advertise that you are looking and wait a little while.

Or send AllClearPG a PM. He has been trying to get people together to do a large order from Oceams Motions so that he can get a wholesalers account with them. I dont know what the price would be through him but it would be less than what is advertised on their site.

My pump has 1.5" inlets and outlets all I had drilled in my tank was a 3/4 outlet I want to run the 4 lines over the top of the tank I can run any size pipe required

Ah sorry I got confused for a moment. Definitely find a 4-Way then so that you can use larger diameter plumbing.

Here is how I plumbed the return through the OM 4-Way on my 120gal. I was partially modeling it after this tank of the month: http://reefkeeping.com/issues/2006-10/totm/index.php

That is ExACTLY what I had in mind.... Did you just leave the PVC fitting in the water or did you use loc line?

Loc line doesnt come in 1" sizes so all I have now is PVC. I had to modify four 1" PVC 90º fittings to get the angle that I wanted. You can see where I cut them and how they are just below the surface in this picture.

If I stand in front of my tank and look at it I barely notice that they are there. They are mostly covered in coraline now but if you really want to make them invisible you could probably paint them blue or back depending on what color your background is.

When I used to use 3/4" plumbing with loc line flare nozzles the configuration looked like this:
