Just moved in to my "new" Used place with a IG plaster pool, the previous "owner" only used triclor tablets in a haywood cl100 feeder. i purchased a TF-100 Kit and a sppedstir. have found out that the cya levels are at least 90 to 100. i was having a problem with mustard alge. slammed the pool per this site. the water is looking good. i have read that the only way to lower the cya is a partial water change... at this point that is impractical to do as i am in Central Florida and on city water with very high usage rates. i am also having issues trying to determine the gallons of my pool as it is a free form type. i will post pictures of the shape and measurements of the pool
my readings as of this morning are
FC 21
CC .5
Cya 90-100
i have stopped using the triclor and have been using the pool bleach from walmart which is 8% or 10% will have to look at the bottle again was pretty dark this morning before work when i checked. ran the pool 24x7 for two weeks to get the mustard alge under control. pool has a screen enclosure and is pretty much in full sun all day. at this time of the year we get almost daily rain . the measurements of the pool are approx 25x13 with 3ft shallow end and 6ft Deep end
many thanks
Bill
