Hello All,

I've found these forums back in 2004 when we first purchased this house and became pool owners. I've always followed the BBB method and it's worked great... until now. Our pool has been green for weeks now and I'm at a total loss for what to do next. Here's some details:
CYA: over 100 to the best of my knowledge
TC: 30ppm
pH: 7.5
In ground, gunite ~25K gallons
Cartridge filters

I don't know if the green stuff is algae or something else. It's seems to be a very fine bright green dust when I brush it off the steps etc.. We have an aquabot and as far as I can tell, it's going right thru the aquabot bag and back into the pool.
Any help is appreciated. Thanks!

Josh
