so even though this product(oxalic acid) states that it is a sequestrant, it is not? i know nothing about pool lingo. The only thing i do know is that i used 32 oz of metal treat(tricurboxylic acid/phophonbutane) , and also 32 oz of metal out(not sure what's in this). With both of these i've had no luck. since i used the oxalic acid product do i still have to add more of a metal out product?
since i've added the oxilic acid my #'s are:
TH:100 (this never changed since beginning)
FC: 0
pH:7.2
TA: 240(highest strip goes) can't seem to get down
CYA: 30 -can't get this up. used 4lbs of stabilizer and cond. last week.
5,000 gal pool
