I have a pool where the levels are well maintained:
FC=3.0 on a regular basis
pH=7.4
Alk= 105
CH=290
The problem is that green algae grows in the seam of the pool(this is a plaster pool) and on the corners of the steps. The FC is maintained at a 3.0, the pool is brushed w/a metal algae brush once a week, there is good circulation, I don't get why it keeps growing back!
The whole pool doesn't turn green, it's just in certain spots. Even with shocking the pool and bring the FC up to 20ppm-it still comes back!
This is a pool that I had inherited 4 months ago, the previous person who "maintained" the pool did not keep up with the chemicals, or basic maintainance proceedures. The pool also hasn't been drained in 2yrs.... Could the only way to combat the algae be to drain & acid wash the pool?
Liquid chlorine is used and there is no CYA-this is an indoor pool with a retractable roof.
Any suggestions to beat the green algae growing in my cracks?
Thank you
