What I see floating is actually the chara that had grown up to the surface and then gets burned by the sun as my water level falls. I lose about 1" per day in hot summer time, and this thick floating stuff peaked towards the end of August. If I am real diligent and keep the water level topped off every 2 days, I see less floating...if I go about 8 days between water fills, then I see a lot more. The floating stuff is gooey and brown.

I had Todd Overton positively identify the Chara, however, it was a fresh sample from about 2 ft of water.

My water stats from 12-19-2007 were:
ph 7.5
alk 140 ppm
hardness 80 ppm

I was hoping that the GC will make a dent in it and my algae bloom will come back. Should I chemical control as well ?


Thanks,

Darryl
