Having previously been using a simple kit from the pool shop ( with the tablet FC test), I figured I better get serious and get a decent test kit. The TF-100 seems to get pretty good reviews so here I am!
1st results and it looks like the pool is pretty close to where it should be. I have been battling algae and after several shocks and plenty of vacuuming, it's finally clear.
I think I can let FC come down a bit now, given the CYA was at 150 8 weeks ago (pool shop test). I have been vacuuming to waste and topping up so I'm dreading the next water bill!
