Just got my pool up and running and the numbers near perfect (my test kit only shows up to "5" as a level of chlorine):
5+ FC & TC
I am using a mineral treatment that I have had great success with the last couple years called C-Pool and once I had the numbers balanced I added my pool opening dosage of C-Pool and had the pump running for 24 hours straight.
Thats when I noticed these patches of what look like darkish green fuzz on the bottom of the pool in some places (mainly under where the jets are and the drain in the deepend). I have attached the pictures, the "algae" I'm thinking of is the dark or what looks like shadowy spots in the pictures.
The first time I saw the patches I vaccuumed them all up no problem but a day later the same amount showed up in almost the exact same places so I'm not sure if its just getting sent back through the filter or not.
Overall the pool water is crystal clear though and if not for these mystery patches of "algae" I would be swimming right now.
Thanks for any advice everyone!
