I have built trash can sumps, and trashcan in pool filters.
I just filled mine with scrubbies. (I got rid of the sponges in the middle because they trap detritus, and just had the plastic floss packed in there.
Even so, I needed to rip out the floss at least once a month and rinse everything out because of how much waste got trapped in there.
Worked well with a heavy bioload though...50+ pacu with no ammonia or nitrates to speak of.
Check valve is in the wrong spot.
Tv on top of your tank? Its one or the other![]()
I actually dont think I need it, but if I did, where should it go?
Your diagram show a check valve on the line that is gravity feeding the trash can. A check valve allows flow in one direction. So if the water is flowing down hill your check valve would prevent water from flowing uphill?. You don't need it here.
If your return line is below water level in the tank, a power outage will syphon the water into the trash can so a check valve on the return would make sense. To eliminate the need of a check valve have the end of the return line above water level.
