Quick background on my pool.
My pool before I purchased home was covered during the winter of 2012/2013 with a terrible pool cover surrounded by trees. Pool was opened (just for inspection in April of 2013 and cover thrown out) and left unattended while we closed on house which did not complete until late August of 2013. No time to start pool before winter, so purchased new pool cover and covered pool as is. Now summer of 2014 comes and I begin my battle (as a first time pool owner). Many hours shocking, back-washing, cleaning filter, adding DE, and skimming the million leafs from overhead trees. Just had it almost clear and left for a wedding in Hawaii for 10 days, came back to a green pool from leafs. Almost get it back again and old pump goes, takes a couple of weeks to buy a new variable speed and getting connected and green again. Lose another pump, but there are points last summer that it was clear even with all the headaches.
Open pool this year and looks much better than last. I have all the trees taken down in the spring, but still in two months can't get pool clear. I've added a ton of chlorine (before I found this forum), I guess mostly Dichlor (Leslie brand, blue seal, chlorox - not bleach) and green out from Leslie's. Found this site, tested my chlorine and PH (only tester I have at the moment) both non existent. So got borax and brought my PH up (7.8) took my water to local store to get tested (wanted to see CYA so I can check the CYA/Chlorine chart). They say numbers look good but chlorine (0.9), but I see that my CYA is 162 and ask if that is a problem (they don't think so)
1st question: CYA is extremely too high correct...............I need to drain at least half my pool?
2nd question: This old DE filter of mine has me concerned (can't buy a new filter now), but it says 8 scoops on the side. Everything I read says one scoop/10 Sqft on the internet. This is 35 SqFt so I think 3.5 scoops should be enough?
Thanks in advance
