Opened to a slimy pool:(

[freddyttt]

New testing done-

PH 7.2
FC 1 ppm (confused to why this has not gone up)?
Combined Cl. 3.4

iv added about 2 gallons of cl. throughout the day. also backwashed a few times as my filter started ton read over 20(pressure)
also, backwashing although lowers the pressure slightly it does rise quick over 20 soon after.?((normal around 12))


please advise.

thanks-
