Difference in suggested levels between Pool School and Pool Calculator

[TroubleFreePat]

Was just looking at the new styling of the pool calculator this morning and noticed the suggested FC levels there slightly differ from the suggested levels in Pool School. Any reason?

At a 70 CYA level, (And suggested levels set to TFP, SWG and fiberglass) pool calc shows -



While Pool School shows -



I've always stuck to an FC of 5, but noticed the shock number if pretty different. . .

You should use PoolMath instead. Pool calculator is no longer being maintained and has not kept up with our latest recommendations.
