After a six hour hard rain last night, these are my readings.
FC 3
PH 7.5
TA 90
CH 120
CYA 40
BR 40
My sand filter (without DE, sand only) PSI has been 17 PSI clean and 18PSI dirty this entire year. Early on I had one day of 13 PSI. I acid cleaned the sand today and the pressure is still 18 PSI. The return water will almost float you away and blasts powerfully agaist my hand. The water stays crystal clear except today because of the storm. I should have it brushed and cleaned up later today.
Waht do you think about the PSI?
