Bromine Chemistry Question

[JimK]

Again, using a PO4 remover ONLY has value if you take the PO4 level down to a measured 125 ppb (0.125 ppm) level OR LESS. Simply lowering the PO4 from 2,000 ppb to 500 ppb is probably useless. Also low PO4 levels only make it EASIER to kill resistant algae; low PO4 does not kill algae by itself.

If you have been successfully maintaining a clear pool on opening without messing with a PO4 remover, using one probably serves no purpose.

Thanks for the clarification.
