Bought a house that has a pool was told the liner had only one season but then a few seasons of disuse and cover was not put on until at least 1 winter without cover. Yes, what a mess, well to make a long story short after an expensive 2 weeks I think I am ready to start the slamming process tomorrow when my test kit arrives. I am inpatient and today had pool store run water test, results:
TC = .6
FC = .6
CYA = undetermined (said could not calculate because ph and TA out of range)
I see in slam instructions ph needs to be between 7.2 an 7.5. But I do not see range for TA before I start slam. I thought I read a thread that instructed a person to adjust both in preparation for slam and the pool store said both need to be adjusted to calculate CYA. Is this true or should I just lower ph. If both, can I add both acid and Baking Soda at same time or do I have to add one then wait several hours before adding the other. Will TF 100 test kit read CYA if TA not in a certain range. It should also be noted that during my expensive 2 week, long story I emptied out two thirds of pool water and refilled so CYA may be very low. Previous owners did however use an in line chlorinator and puck dispenser (actually 2 dispensers are here), so there should be some CYA.
PS. Great site, after we bought this house I was reading about all the ill affects chlorine has on health and how you should put a whole house carbon water filter in your main water line so you would not absorb chlorine through your skin. If I read Chem Geek correctly chlorine is not absorbed through the skin. He is very knowledgeable and documents his references frequently to support his position. I was thinking about filling the pool in until I read a lot of his posts. If Richard has any time to comment on chlorine being absorbed through skin and ingestion of chlorinated (non filtered) water as a health hazard I would be very interested. He is this sites greatest asset, not that everyone else isn't, but very impressed with his knowledge and stick to the facts approach. I just do not know where he finds all the time to type this, let alone research it. Thank you everyone for your time and willingness help.
