    Hello and welcome to TFP. I'm assuming this is green from just opening from the winter closing correct? If it's algae, which I suspect it is, then you will need to SLAM following the directions on the SLAM page (link below). Key factors include adjusting pH to 7.2, increasing CYA to 30, then maintain the FC at 12 day & night with pump running and following all the directions on the SLAM page. Make sure to have your TF-100 or Taylor K-2006C test kit handy for all the testing required as you go. Let us know if you have any questions. Good luck!
