I have had my 29 gallon office tank set up for about 18 months with a bulkhead in the back and a basic drain/sump system. Yesterday, I noticed salt creep/ splash marks in the area behind the drain, where there is a "T" with a drilled cap. The water used to just drain through the pipe evenly, but now, every few minutes, the "T" starts gurgling, and spurts a bit of water through the holes in the cap. I checked the drain for blockage, and there seems to be nothing blocking it. The bottom of the black drain tube still pours out a lot of water into the sump.
Here is a photo I took today... any ideas about how to solve this problem? One thought I had was to add a vertical pipe, plus coupler, then the drilled cap. That way, the water gurgling up would have a greater distance to travel before reaching the holes in the cap.
