My pool details are in my signature below. Also, here is a list of the chems I just got from my pool store:
FAC : .26
TAC : .37
CH : 553
CYA : 174
TA : 78
It was recommended that I use 5 lb 15 oz of soda ash to raise the pH. Also, that I put one lb of liquid chlorine to shock it up to normal then have 2 3" jumbo tabs in the floater.
The chems aren't concerning me as much as the pressure (psi). Before and After back washing, my PSI is running at 30. This was advised to be very high by my pool supply store. The only thing he could recommend was a new pump, which runs about $1,000. So I figured I would come get some subjective advice to see what else I may be able to do to lower the psi before going all in with a new pump ( which doesn't even seem very old to me). Although, I just bought thr house and have no real way to validate the age.
Any advice that anyone could offer would be greatly appreciated. Thanks much!!!!!
