I have actually done this: (ASCII art alert)

The inline water filer also acts as a bit of a check valve, mainly
because I couldn't find any brass ones available locally.

I was actually wondering if the frosted glass effect could be a sign of
green water, which soneone has said in the past is not nesecarily green.

Anyway, 2 20% water changes 12 hours appart seem to have solved most of
the problem so we'll see what happens of the next few weeks.  Maybe a
few more plants (a java fern or 2) would help?
