I am trying to do the decontamination process from Nitro. I have already done the enzyme part and dumped that. Now it's filled and I am trying to balance it to the TA of 80 and PH of 7.2. I've got the TA at 80 but nothing is getting the PH down. I just bought the test kit K-2106. The PH is showing at the highest level, and I only have to add 2 drops and it turns pink. So I check the book and for my 350 gallon spa I calculate that I need .63875 oz of muratic acid (18.89 ml) I do that and come back a few hours later or the next morning and test again. It gives me the same thing - high PH and 2 drops turns it pink. I've done this 4 times now. The only thing differently that I've done is that there is no filter. I accidentally missed the part of throwing the filter into the spa when I put the enzyme in and have a new one ordered. I didn't think it would be a good idea to put the dirty one back in. (The spa set with water for over a year - covered on a covered porch. Water was still crystal clear.) Any ideas on what I should do?
Hi, Been reading the forum a bit more now. The following question rose to my mind. Wouldn't testing these 4 parameters suffice (for my pool). My pool being plastic above ground, outdoors and no splashing, pH elevating fountains or such. CYA: test CYA to reach optimum level. pH: test the pH and correct pH with hydrochloric acid or sodium bicarbonate when necessary. FC: test FC and correct with bleach. TA: test and correct with sodium bicarbonate. The amounts of HCl, NaCO3, trichlor and bleach needed will be calculated with pool calculator. 'Correct' me if i'm wrong, Tim
