thank you for answering so quick! I will go tomorrow and get one of those kits. I don't think the chemistry has been quite right since the pool was installed and I really want to try and do this myself, I just feel so darn nervous about it!
there is so much I don't know and things like getting the lid off and on the filter (a whole other issue we've had) and have no idea how to clean the salt cell and on and on! LOL again thank you!
