Well, it seems the treatment was successful, due to the nature of the parasite I won't be sure for several weeks (not my first go around with this nasty.) As far as the plants go, it appears I have a small diatom outbreak, brown stuff on leaves and filter tubes, seems to be clearing though...I can't say that it's due to the levamisole or the CO2 issue, (could be both, without a way to isolate I'll never really know
) but i do think things seem to have slowed as far as growth is concerned, particularly the rotala which coincidentally shows the most as far what I think are diatoms. We'll see how things go after a couple more weeks of WCs
Needle valve seems better now, cleaned it and increased service pressure a little. Sumo set up is on my wish list, we'll see how that goes........
