That pro kit seems to be a bit much for me — I am only one my first month of pool ownership. Would you recommend the other one on the list you sent?
If you're talking test kits, the TF-Pro is the best deal given the amount of reagents you get and the nifty case and SmartStir. You don't need the SmartStir but after about the third test you'll wish you had it. Don't buy the salt test or the pH meter. Having a good test kit and following the TFP method will pay for itself many many times over versus getting pool stored. Spend a bit now to save a lot later.
What chlorine would you recommend?
Liquid chlorine or get a Salt Water Chlorine Generator. Do not use tabs or that stuff you're using now.
