Good Evening everyone. First I want to say how happy I am to have found these forums. My wife and I just purchased a house with a preexisting In-ground pool and its been a steep learning curve so far. These forums have been invaluable.
I've already had a couple of less than pleasant pool shop experiences, but with the information I've learned here, I feel I wont have to repeat those experiences. With that being said; I do have a few questions, the answers to which I am hoping will assuage some of my wife's concerns.
1) Based on my pool size (18' x 36') and approximate gallonage (26750) I've been keeping my FC levels right around 3 or 4 with TriChlor pucks. My wife is concerned that, at those levels, the chlorine will cause the vinyl lining to age prematurely. I have read that vinyl is non-reactive, but the previous owner of the house, our 'former' pool guy and the pool inspector all said that those levels of FC will adversely effect the liner. Can anyone clarify this one way or the other please?
2) One of the modifiers to the above concern is that we are running a "frogger" in line, along with a Trichlor stack. I was told by the previous owner and our former pool guy that the "frogger" gets replaced at the beginning of the pool season. Of course, I want to go away from the TriChlor pucks, but I am wondering what the interaction is between this 'frogger' and the CYA the pucks are putting into the water.
3) I appreciate the automation of the TriChlor pucks. Is there a recommended automatic system for Liquid Chlorine that I can use to replace the TriChlor stack?
Thanks, in advance, for taking the time to read and provide answers.
