I have a 23K gallon, vinyl lined, in-ground pool, with a Hayward pump and 300 lb sand filter. Water is green with algae, even though my water condition is good (pH: 7.4, Chlorine 5+, TA 100). Pump is running 24/7. Shocking every few days to try to get rid of the algae. Even changed the sand out in the filter to the zeo-sand.
Been getting advice from a pool maintenance guy and he says that since I am maintaining balanced water, the problem is filtration and he suggests I switch to DE. That's a high dollar commitment on this pool.
Not sure why all of a sudden the filter does not work (had the pool for 3 years and no problems, now green water for 2 summers straight). Any suggestions?
Should I go with the DE?
