Had 15 x 30 oval AGP installed 7 years ago- well that's half IGP and half AGP
Since I am in similar trade did all the underground gas, water, and electrical work myself
Kind of funny when people jump in thinking pool is only 2-1/2 high
Been following TFP for 5 years, wife found the website and told me to check it out
Switched to liquid chlorine shock usually from menards when they have 2 for one sale, have chemical pump with 10 gallon tank on timer works very well very little work
Never have had to shock or slam, pool goes to bed in fall crystal clear, wakes up in spring crystal clear, fill, adjust levels, turn on heater, enjoy
Installing new Raypak heater and variable speed pump motor (VGreen) this year. Had started out with used heater
Also going to try borate to see how that's works
We had minus 25 degrees below zero here this winter hope pool is OK when we uncover in a couple weeks
Thanks for all the help
