AndreaW Posted April 2, 2022 Share Posted April 2, 2022 I'm trying to find a rigid tube that has an inside diameter (ID) of 3/4" that will attach to the outlet of a powerhead, that I can drill holes to create a DIY spray bar. Each powerhead is rated for 145 GPH, for a total of 290 GPH. I haven't figured out what size holes and how many I will need to have to soften the flow of water yet. I'm thinking that if I can find a tube that is rigid, I can turn both powerheads toward each other (along the back wall) and have the tube connect them, I can create a whole wall of flow, rather than the concentrated flow from the two corners. So far, I can find 3/4" ID silicone tubing that is flexible, and 1" rigid tubing, but I haven't found a source for 3/4" ID rigid tubing. I think the uplift tubes are 1" diameter, and that would work great if I could find a piece about 36" long, but a 3/4" should work perfect without having to find something to adapt. This is the powerhead outlet with the flow diffuser removed. It is round, and seems to be exactly 3/4". This is what I have in mind. Powerheads (in red), facing each other. Rigid tube (in green) suspended between the powerheads with lots of holes for water to flow out of. I found some polycarbonate tubing many people use for light sabers, but I don't know if that's aquarium safe and some people said it looked a little cloudy. At this point cloudy isn't as important as just finding something that will work. I'm sure it will just grow some algae anyway, like the uplift tubes, which I need to replace as well. I'm confused as it says it is 1/8" thick, 1" OD, 3/4" ID, which doesn't add up... Link to comment Share on other sites More sharing options...
