I have owned a pool for 25 years and have had minimal problems until about 2 years ago when it just seem i couldn't say ahead of the algae. Yesterday after reading a post on this web page I realized that I had forgotten the critical steep of cleaning my sand filter. I opened it up and found the bottom covered with little tree leaves. The leases are small enough to get sucked through the pump filter. I cleaned out the leaves. and stured the sand as suggested in the channeling thread. I started down this path because the pressure keep dropping to near zero. Like i said in the title currently my pool looks green from top to bottom.
The ph is 7.2 and the chlorine is +5 pmm. shocked.
I made sure the impeller is clean. Now the pressure stays at a steady 10 psi it doesn't go up even after 12 hours of continues running. When I backwash the water stays clear. I check the water coming out of the aerator and it dose not appear to be any cleaner than the water in the pool.
At this point in time I am at a complete loss. The only thing I haven't tried is adding the DE to the pool filter. This probably will help but I feel that there is something I am missing that is systemically wrong (the filter dose not appear to be cleaning the pool).
I just want to clean the skimmer basket. I pulled the valve from the bottom. The pump does not appear to be pulling as much water as it used to. First in the past when I pull the valve is was much harder to get up. Second in the past with the valve removed and the pump running the pump was able to draw so much water out of the basket area that it would start sucking air. Now the basket area stays full of water.
