I'm a new homeowner and after a miscommunication about who was adding chlorine to the pool, it's now green. It's been green for about a week now and I've been testing the water with the test strips the previous owner left us and adding extra chlorine and some of the algy stuff the previous owner left us.
While researching what else to do to fix it, I found thirs site. I have been reading a lot of the threads and just ordered the Taylor K-2006 test kit so I can test the water myself (it will arrive next week).
With everything I have read so far on this site it sounds like I shouldn't add the algy killer anymore and I need to go buy liquid chlorine to use instead of the granular chlorine we have.
I know there is not a lot you can tell me before my test kit shows up but I do have a question about chlorine. The pool store told me that liquid chlorine is bad because it adds a lot of salt to the pool, and this site says that the granular chlorine is bad because it adds a lot of CYA to the pool. I understand that both salt and CYA accumulate in the pool and the only way to reduce them is to drain and replace some of the water. There are explanations about the down side of too much CYA, but is there a downside for having too much salt?
Thanks in advance, here is a picture of my pool from 4/5/16.
