Hi there, I have been battling my pool for several months and after 'slamming' had the dreaded return of the mustard algae. I then realised I had not gone to the mustard algae shock level so had to start again. The pool is crystal clear and I think I have just about seen the back of the algae.
OK the questions are:
1) Where do I get a proper test kit in Europe - the only place I found in Spain wants 150€ Taylor K2006 which sound extremely expensive but I don't really have any idea. Can they be shipped from USA?
2) I exchanged around 35% of my pool water to reduce high CYA from 150 to around 100 (strips appeared to confirm this) but after shocking for several weeks the reading for CYA appears to have dropped to 30-50 - is this because the FC is still too high to give a proper reading or can this be true (FC is currently 40-50 and dropping but has been as high as 60)
I admit I have been bundling along doing OTO tests dilluted and verifying with test strips with the same dillution, but it seems odd that the CYA has dropped so dramatically (the CYA was tested undilluted)
I know I will get slapped wrists and am sorry to be using the Aquachek test srtips and a basic OTO/PH drops kit but I am struggling to get the proper kit here in France
Merci en avance
Peter
