Tricolor pucks are acidic and will drive ph down
TA only buffers ph at the lower levels so if you have an issue with ph rising tfp recommends keeping TA lower in order to use less acid to maintain ph

Only backwash when flow decreases 30 percent from original clean filter flow. A less accurate method that works is checking when psi is 10 above clean filter psi (21 since clean filter psi is 11). Backwashing too often can cause poor filtration.
