1. remove the 4" tube and just hang it on the drain pipe with a string or make a holder a couple inch below the rim of the sump and let it sits on the holder only. this will increases the flow through the socks and you could see if it dirty ect..
How did you support the pegboard/drip tray? I see the pvc underneath but I can't understand how its supported on top so it doesnt move with the water pressure?
Next step was making the area for the biomedia. I constructed the bottom and the stands for it out of egg crate. I then used pieces of pvc on top of the egg crate to hold up the drip tray. I made the drip tray out of plastic pegboard. Once all is said and done I will be using polyfill mat on top of the drip tray.
