I have persistently high TA readings, 300 to 400. Ph is stable, 7.3 to 7.7 as are FC (3-6) CH 130 and CYA at 40. Water is crystal clear and tastes and smells fine. My testing may be at fault, I use a Color Q 7 tablet version (I know, I know, but I can't get Taylor here in Italy and no one will ship from the U.S.A.).
On standard testing (one tab to 50ml water) TA just reads 'Hi' (over 300ppm) so I double up the sample to 100ml and double the result, is that the way?
In any event the TA is high and I know I should lower Ph and aerate but this is technically difficult with my returns located in the bottom of the pool and I've given up producing children for splashing purposes, although have a newly baked grandson who should be ready for duty within a few months...
Before embarking on producing some kind of separately pumped Heath Robinson fountain I wonder if I'm trying to solve a problem that isn't a problem as the water is good on all other objective and subjective criteria. The grandson thing is relevant because he will be dumped in the pool shortly and I don't want any adverse skin reactions, although the water does nothing but cool and refresh my wrinkled old hide.
Any ideas gratefully received.
