My pool is very cloudy. I have spent hundred of dollars on shock. metal free, phos free, pool perfect. etc with no discernible results. I also dove down to the bottom of the deep end ( which we can't see from the surface and there appears to be a slim covering of slime and algae. Finally, my filter , a Hayward DE4800, no longer manufactured, spikes up to 20 PSI almost immediately after backwashing and I lose all suction and power to the jets. As you can see, I have multiple problems and need some serious assistance. Please Help!
