    Hello, Been a few weeks since I checked in. Had spraying issues redid another manifold and installed a spray guard.Still have the brown stuff. I do have some green but its right at the top inside the manifold. I'm considering building another box. The acrylic I used was not exactly clear. I could be restricting the light.This pic after a serious scrubbing. thanks

    Thanks! Will do. Also I have had issues keeping the 18/ 6 lighting schedule. My fault. This is an experiment to me. I'm in no hurry to get results. I am enjoying the challenge and learning the best way.

    Good Evening. I did a flowrate test today. The screen is 7 inches along the top. I came up with 28.2 gph, Not enough. I removed the screen and got 36 gph along the top,still not enough. I propose to widen the slot before I look into a bigger pump. I know I should have tested flow but thought for sure the pump would be plenty. Here is a pic Please note the green right at the top of the screen this is inside the manifold. Thanks!

    Is that 28 GPH per inch, or total? Widening the slot should not be needed unless it's less than 1/8", or not even.

    I was asking cracker if his measurement was total GPH or per inch. Hence the reason I quoted his post

    The figures posted are per inch. I understand the need to clarify.When I ran the test without the screen, The water blasted out along the entire slot. I "hope" the pump is restricted by too small a slot. we shall see. Once again this is an experiment and learning how stuff works. Thanks. Brian
