Just because I'm a nerd and I would do things differently now, I want empty my pool and start again using liquid chlorine (instead of this horrible trichlor), and some borates (just for fun) and more controlled set amount of CYA.
I know this is a basic question, but what kind of pump do I need to do this myself, and where do you normally buy them? What would a good prosumer brand be?
Also, my pool has been in operation for a year now. Is it safe on plaster to empty and refill it right away?
Picture of pool attached, since I heard you guys like pics.
