Custom spraybar

Here are spome pics of my spraybar. It has a bulkhead on each end and I have a 5/8" y (not a T) to pump water into each end to get as even of flow as possible. I am trying to decide if I want to drill it or cut slots in it. Opinions please.

I drilled holes in mine and am impressed with the results.

from about 3 months I discover the benefits of a good spraybar!
I ordered one for my aquarium and thinking to do it for my other one.
I think the hole version is better !

Did you cement the parts together?

For mine I decided not to do that in case I want to change the angle of the holes later.

Just a thought...

If you want more pressure drill it. If you want less pressure but more flow, slot it.

I am going to be using a Rena XP3 and a 3 foot Rex style reactor on this. It is 1" pvc so any ideas on hole size?

It's hard to give the advice without the actual setup. The inline stuff really affects the flow. When I put my 2213 in my 15 gallon, I ended up enlarging the holes twice to get the exact flow pattern I wanted. If it's easy to dismantle, I would just test fit it.

Start with about a dozen holes, 3/16" drill bit. If this is too restrictive, if the spray is more like a jet (it probably will be) you have a couple of options:
a) Enlarge each hole. Spray will be gentler out of each hole, less chance of crud blocking the holes. Yes, this is after the filter, but still, stuff can get through.
b) Add more holes. but there is still the possibility of any crud blocking the holes, these are small holes.
c) Connect the holes you have with slots that are parallel to the pipe. This will create a more sheeting effect, especially if you can sand the edges for a smooth flow. I would probably not connect ALL the holes all the way across, but connect them in pairs, so there is a slot, then pipe, then a slot, then pipe... If this is not quite gentle enough then make more slots. The thinner the cuts the more forceful the water will come out, but the more slots there are the gentler the flow. Again there is the risk that a really thin slot will collect a bit of debris.
d) Turn each hole into a slot at right angles to the pipe. Same comment as c). Small slots = more force and might collect some debris.

Diana, I was planning on 1/4" holes at different angles. one pointing down about 20 degrees the next @ 30 and then 45. Trying to get coverage at in different areas.

Definitely do not cement it together. Gunk does build up in my DIY spraybar and I have to take it apart in order to clean it properly.

I was not going to. Just in a couple of places so it will not sag.

Calculate the area of the outlet of your pump: (Pi)(Dia^2)/4

Decide on your hole diameter. Calculate the area of one hole.

Divide the hole area into the pump outlet area. The whole number of the answer minus one is the number of holes to drill to put least resistance on the pump.

Using a Mag 7 pump and Mazzei Injector for the CO2, I drilled (35) 1/8" diameter holes in my 3/4 PVC and was very pleased with the results. Don't deburr or chamfer the holes on the outside of the pipe or else you will end up disturbing the flow and getting a spray pattern from the hole. You can run a file flat around the diameter of the pipe to remove the small burr if any.
