White. About 20 white spots randomly spread over his body.

I can almost see torches and pitch forks waving while I write this, but
I'd vacuum the plenum after the white spots drop off. It's not really a
cure, but it may help you break the cycle w/ the help of your shrimp
friends.

I did that with mine, and I haven't seen Ich since. It also pulled an
amazing amount of crud out of my system, and I just have a thin sand layer.

I know my English is not perfect, but what the hell you call plenum? :-)

My tank is DSB and I am not going to vacuum fine sand out...
Vacuuming would not work.
