So I am new to pool ownership. I have a 24k in ground pool. Have been using the BBB method since I opened the pool in April. The problem I'm having is I keep getting yellow is deposits on the plaster. But I'm not sure if it's alge. It brushes right off. I did an ONCT and only dropped 0.4 ppm and CC is 0.2. The water itself is clear. Any ideas?
