So, I finally found a pool service that is coming out tomorrow to replace the broken lateral for me... whew! They suggested and I figured it was a good idea to go ahead and change the sand since I bought the house last year and don't know when it was last changed and since they're already gonna be "in there" might as well.
He suggested using Zeobrite and said that even though it's more expensive ... you don't have to replace it as often as you do sand so it works out in the long run. I told him okay but then later googled and found that 50lb bags of sand are less than $10 and I need 3 bags of zeobrite @ $25/bag plus the website says it lasts "just as long" as sand... nothing about longer.
So any thoughts on the benefits of paying so much more for this stuff or should I just have them replace with sand?
