New Intex above ground owner - Psuedomonas?

[May76]

Just checked the PH Rise and it says that the active ingredient is "sodium carbonate" it does not list anything else. I think Pool Doc said I wouldn't have to buy the Borax since I have the PH Rise, that it is same as washing soda just more expensive? I could have misunderstood him though. Last time I used the Ph Rise it went from a PH of 7.0(pool store reading) to around 7.8(7.8 was my test strip reading), but the pool store tested it a week later and it was 7.4. I added about 2 cups then(if memory serves me correctly) so I may use just 1 cup tonight if it's ok to use and see where that takes me. I would prefer not to use Muriatic Acid to lower again it if I don't have to.

EDITED TO ADD:
ok, went ahead and added one cup of the Ph Rise, will test in a couple of hours and see what the results are.
