Probably just a bactrial bloom that will go away of it's
own accord, when the bioload and the surface bacteria and
plants are all roughly in harmony. Right now you probably
have a surplus of "messy brown stuff" and the surface
bacteia and plants can't keep up. The sometimes occur after
the first few weeks and last for days or weeks. If you add
a flocculant, it might clear the water temporarily.

I might be reading you incorrectly but it soulnds like
you're rinsing the filter media into the aquarium system.
If so, then do this, take some water from the sump or
aquarium and put it in a bucket and rinse the sponge in
there, then dump that out. You want to remove all that
"messy brown stuff" from the aquarium water system; rinsing
into the sump won't do that, although the water change
right after helps some.

Javas will do that.

If nitrates are measuring only 5 -10 ppm, but you have
ample light and you're adding CO2, trying adding 50% more
ferts- say halfway between your regular dosing. If that
seems to help, you even try a little more. Keeping up water
changes and removing from the aquarium what collects in the

I don't know what the phosphate limiting level is with
Watson's PMDD but I wouldn't wouldn't try to limit plant
growth by limiting the phosphate -- that always made my
tanks go goofy. 

Good luck, good fun,
