First off what a great website / forum!!
I am new to pools and want to keep the water balanced in all areas. I have read the ABC's sticky thread about target ranges for each parameter of pool chemistry. The wife and I just got a pool up before memorial day weekend and I have at the moment a high free available chlorine level of at least 4 ppm. This is as a result of me adding a 1lb bag of (Pool breeze) brand granular shock treatment which is of the calcium hypochlorite variety. Today I decided to go to my local Leslie's pool supply and have them look at my water sample and the guy said my chlorine level is too high (bleached out) to get an accurate reading of my pH etc.
I had some questions about my CYA as I want to make sure to have it at the right range as well as what form of chlorine to use. I told the guy at Leslie's that I had the calcium hypochlorite form and he said he did not recommend it as it could build up the calcium in my pool I believe he said.
So my question to you here at the forums is:
First off do you feel the calcium hypochlorite form of chlorine would be less desirable than say another variety?
I see that Leslie's carries 3 in jumbo tabs of trichlor 90% available chlorine.
If I wanted to switch forms of chlorine from the calcium hypochlorite form to the type in trichlor do I need to take certain measures in this transition?
After I get this issue sorted out do you all just recommend I use a floater for regular chlorine maintenance between weekly shocks or what is the best approach in your view?
I thank you all in advance for your help in this matter.
