Best DIY Spay Bar For Planted Tank?
I am looking to make a DIY spay bar for my Co2 Injected tank, I use a Fluval 405 with an Inline atomic diffuser for Co2. I want to make a spray bar out of PVC Pipe, and Elbow, And a Cap. What is the best way to design the holes in order to get the co2 pushed down into the water the best? also can I some how make it black? Or would using an Knock off lily pipe be better?
