Now a question: How to keep the stuff at bay? Here's the set up:

55g tank, 48L 20H 12W
pH 6.7 with C02 injection at 20ppm
KH 3deg
temp 79f
Nitrates between 5 and 20, fluctuate with the amount of KNO3 I add.
Potassium and Phosphorus added minimally per the dosing pages. I shoot
for the optimun amount. There are a couple of plant spikes (trace
elements) deep under the large plants.

I've got 5 ottos in there, and just added a couple of large amano
shrimp, but those critters aren't going to touch this fuzz stuff if it
comes back strong like this past week.
thanks for any hints, suggestions,

Are you over feeding? It doesn't sound like anything other than that to me,
unless there is something in your water out of the tap.
