Spray Bars

[AcuraCl1]

Anyone use a spray bar for a return. I thought about using a loc line spray bar as a return, that way I have several little output along the tank to disperse flow.

the return on my 29 build is gonna be all over the top & be a combination of (2) regular loc-line returns at the back & a modified version of Calfo's around the top manifold

for my return i am coming 1.5" from the pump to the bottom of the tank. there will be a t-fitting there going to each back corner w/ another t-fitting.

the "inner" each of these be reduced to 3/4" & go up & over to the loc-lines in the back (drilled over the tank w/ anti-siphon holes). the "outer" of each will be reduced to 3/4" & go up & over to the inside front w/ a t-fitting for input. out of the t-fitting will be pipe that runs down the side & front w/ t-fittings in each for loc-lines in various directions

for the ones on the sides, i'll probably use the flow accelerators i have & point them at the back rock wall to help keep it from getting detrius built up there

something like the following pic. green is the overflow box, red are the sprayers, grey are the rear over the top loc-lines

I was looking at using part number J10 from the link below.

interesting......

I was thinking of using one of them, but putting some spacers in between the locs with outlets to give more space between them, since my tank is 5ft long.

I have seen them in use. They do work, but often they are great at moving surface water, but you get into issues down low. SO I would modify a few outlets to run deep and have locline to adjust direction, ect..

One other thing I would suggest is adding a valve to each output to adjust different areas for flow. It also can be used to allow you use of a slightly smaller pump if you wanted.

Just an opinion.
