Okay. I added about 2/3G of MA last night. I just took my pool sample in. Their results:
pH: 7.7
TA: 232
Adj TA: 232
Total Hardness: 174

They had me put in 3 qts of Pool Magnet Plus. There are NO ingredients listed on the bottle. I hope it's the same as Dave's description of Metal Magnet Plus.
They wanted me to put in 24 oz of Smart Algacide. I said no to the Smart Algacide because it's like 60% copper or something and I read somewhere on forum NOT to use copper. I asked for the Algae All 60 but they said that they no longer carry it. Instead they gave me Inhibit Back-up which is:
30% Alkyl (C14, 95% C12 3%, C18 2%) dimethyl benzyl ammonium chloride, and
10% Alkyl (C12, 61% C14 23%, C16 11%, C8&C10 2.5%, C18 2.5%) dimethyl benzyl ammonium chloride
60% Other
There is no mention of anything sounding like "polyquat".
They also said these additions would lower my pH so not to add more MA for now.
I am off for the weekend so we will see how it is on Monday but I will check in to see if you have responded with any comments.
Thanks!
