The local pool store test has shown that my water has a reading of 2500ppm of phosphates.. in reading this forum, I understand that it is nothing to get alarmed about and not to buy some random chemical from the pool store, but I do notice I get algae spots, if my chlorine level is a little on the low side.. I did recently add a SWG to have more consistent chlroine levels.. my question is, " would it be helpful to add some poly 60 algaecide as insurance to my water?"
The source of the phosphates is a large tree with lots of trash in the spring.
my most recent readings are: SALT: 4000ppm and matchs recommendation from SWG manufacurer
FC 4.0,PH 7.6, TA 80, CH 330, CYA 60... I am adding CYA to raise to around 75
What would be the best way to lower my CH?
