100% agreement on what Swampwoman said. Especially waiting till next season to see what semi automated system you like best. Been many complaints about liquidator and some where it works fantastic, but most either go Steiner pump or SWG. I am still collecting info to see what I want eventually. Been leaning toward SWG and since I now know that is how Swampwoman went lean there even harder, but pros and cons on both. I use chlorinator with 3" pucks for vacation. Just know your CYA level and adjust accordingly, If it will get too high, empty out some water before you go. The big thing is know what you put into pool is going to do before you put it in. This is not an option for some who can't do some water exchanges. Also because we are in the northeast, you will see significant drop in CYA over winter.
This way you have time to educate yourself so when you buy you, you buy what is best for you and do not waste money.
Solar cover works with heater to retain heat, decrease your heating bill. My 12 ml is going to last 3 years, this is last , hope it makes it
