OK I am new to this site. My friend sent me here after her good results with your BBB system. I am using her TF100 test kit and ordering mine tomorrow. I have had algae for a week and tried the pool store and have not had any results and spent lots of money. So here are my numbers. Can someone please tell me what to do next?
From what I have read on your site I think I need to shock as recommended using your How to shock guide.
