Nice tank Chen88..... look great!! lots of work you have on your hand.
Theo, have you had to clean out or maintain your flow valve that you got with your tenecor system? for each line into the tank my system came with a flow valve and a ball valve..just wondering if I should install both....Vince mentioned about cleaning the flow valve often.....
The history of my old 150 gallon Tenecor and sump is as follows:
Set it up spring 2006, used it for 6 months with sump, then I took it apart; tank remained apart for one year, then was set up again for one year, but without sump (Kenta called it a leak factory ). I finally got around to setting up the sump again last month and it is working great. I have never cleaned out the flow valve/ball valve, but then again I have used the equipment so little that I wouldn't know whether it will eventually need cleaning,
Here is a photo of the tank when I first got it:
