I just setup a homemade system and need help with too much water flowing in or not enough flowing out...
I'm using a power-head from the aquarium to fill (4) 4" PVC tubes in an "S" pattern that will hold the plant baskets. It's a 1/2" ID line into the first tube, then each tube is connected to the next with 3/4" ID tubing. The last tube empties back into the aquarium via a 3/4" ID tube as well.
When I first ran the setup as described, it didn't flow through the 3/4" tubes quick enough and ended up rising up through the first tube's basket-holes. I then tried putting a valve between the inlet and the first tube to throttle it down, but it only either just delayed things or had to flow VERY slowly to keep from rising.
I'm wondering if I need to elevate the inlet side of each tube, use a bigger size connection between tubes (perhaps 1" or 1 1/2"), or something else?
Any suggestions? I'm assuming this type of problem isn't that uncommon. At least I hope I'm not the first!
