Hi all, new pool owner here. my pool is one year old and I have been using a pool service to take care of everything to this point. after finding this site I decided to start educating my self on how to take care of it my self. I have purchased the TF-100 test kit with salt test and this is my second day of testing. the water looks fine and nothing growing in it. I do see white flakes floating around, thinking that is from the IC40. (not sure) also I'm not sure what to make of the readings I'm getting.
CL= over 5 PH= 7.8 FC= 7.5 CC= .5 TA= 100 CH= 660 CYA= 40
CL= over 5 PH= 7.8 FC= 9 CC= .5 TA= 90 CH= 590 CYA= 30
salt test= 3000 and my IC40 is reading 3400ppm and have the pool running 10 hrs a day.
after yesterdays test I added 8.8oz muriatic acid per pool calculator today it tells me to add 9.6oz. and I don't know what to make of the CH level..the pool calculator wants 50% of the pool water replaced. also looks like I need to raise the CYA a bit. am I in the ball park here or is this not how I should be approaching this. for some reason I'm really having a hard time with my pool being one year old and needing to change out 50% of the water. we do have hard water in this area but not that hard..I've been battling the calcium ring so I suppose 50%of the water has got to go. my pool service want me to start using BioDex to take off the calcium ring and the local pool store wants me to use phosfree because my phosphates are over 2000. is see from this site that's B.S. any thoughts on the BioDex for the ring??
Thanks in advance.
