I have a new pool that is one month old. 18,500 gunite with pebble plaster. I hear conflicting stories regarding phosphates in pools. My chlorine levels went to zero this week. Pool builder said check phosphates because it can cause low chlorine readings. I have several questions for you guys/gals.
1. Should I even be concerned about phosphates levels if I have no visible algae. Does high levels consume chlorine? I have borates in the pool and that is supposed to help with Algae, right?
2. I see on here about FC to CYA ratio. Is that something I should go by? Of course, no local pool company has ever heard of it here. I have an ozone system, does that change the ratio?
Also, I live in SE Texas and water temp stays around 90.
Thanks,
Kurt
