Review on Eheim 4005310 Spray Bar Set: Enhance Water Circulation with 594 Tubing by Karla Garcia

I'm very impressed with this. Well made and easy and flexible installation. I know it's expensive, but it's really well designed - it wasn't worth my time building it myself. I adjusted it so it doesn't affect the maximum flow of my Fluval 407. After some "experimentation" I did the following to ensure flow and spray uniformity for a three part assembly: first section (near feed) , drill holes slightly larger to 9/64, the other two sections are slightly larger to 5/32. (The shipping holes were 1/8.) I highly recommend it.
