I got my new tester today (pool exact Z), i can source the recommended kits here in Cyprus but would struggle to get the reagents imported, so went for the photometer route.
So, i did my tests and double checked these by getting my water retested at a pool store. More or less the same, give or take a little bit.
Pool temp is 80 degrees and air temp is 85 degrees but that will rise to above 100 in the coming weeks.
Pool is clear and blue, i am now in the process of draining 80% of my water to get the CYA down to more acceptable levels,
The biggest problem i have here is getting a decent strength bleach, the highest concentration i can get is less than 5%.
I suffered last year with algae and now i know why!
What will be the best way to sanitise my pool? do i stick with 90% trichlor pucks or go another route, calhypo and trichlor or stick with the weak as pee bleach?
