So i brought a TF 100 kit last season and had very minimal maintenance with the pool aside from occasional chlorine and adding a sock full of something (don't recall chemical name).
So i left the pool half full through our WI winter and opened it about 2 months ago. I shocked it and it cleared up pretty good. Added a sand filter vs. stock intex unit. Now the only thing i've been fitting is keeping the bottom clean. We have zero trees to speak off so all the stuff on the bottom looks like dark dust bunnies like you'd find in your house. Seems like it comes back in a matter of a day or 2.
So i dug out the TF-100 kit and here are the results:
Ph 8.2 (using basic test)
CYA 20 (i could still faintly see the dot with the tube filled)
So i have 4 gallons of shock sitting in the garage and no other chemicals. So i really don't have a preference on which system i use...whatever is quick and easy so i don't have to keep vacumming
