Ok, so I'm lost. I've cleaned out the sump, sand & I'm letting it dry at this point. Nitrate is still testing @ 40, but my phosphates went down to about 5. In did several 15g water changes, but hasn't seems to make much a a difference.
Now, my intake valve drains water from DT, down the tubing, into the black box over the right side of the sump. Inside that thin box, there is fine media padding. I get the return pump should be in a different chamber than the skimmer and I agree, but being that I do have that piece covering one side of the sump, it's not possible for me to run a hose & return pump... Am I missing something, or not on the right page, cause honestly I'm feeling a bit stupid at this point.
