My pool builder recommended for me to put in 2 gallons of Muriatic Acid in weekly to help with the white streaks or "creaming" on my pebble plaster finish. When I did that today it has messed up all the levels. I wasn't going to test the water today except there's been a very strong odor since I poured the MA in the pool this afternoon. The previous weeks I haven't smelled anything. I tested the water approx. 2 hours after pouring in the MA.
pH - 7.0
TA - didn't get a result b/c the water turned red instantly instead of green first after using the chemicals for that test in my kit.
FC - 5.0
TC - 5.0
CYA - 70
CH - I didn't test it.
Yesterday, my pH level was perfect so I knew pouring in the MA would mess it up. I reduced my SWG to 40% since my FC & TC level are too high. Should I just add baking soda and soda ash to help with the pH & TA? Is this something I'll have to do weekly if I continue to do the MA treatment for the plaster finish?
Also, yesterday I used a product from Leslie's called Pool First Aid b/c I noticed we were getting a build up of oil from sunscreen and some kind of scum on the top of the water. Leslie's also recommended Fresh 'n Clear. So I used those 2 products in the late afternoon but not at the same time. Did using these products mess up anything I did today? Is it necessary to use Fresh 'n Clear on a weekly basis? The worker at Leslie's said it's a treatment that I should use weekly since it's the summer & it's a non-chlorine shock.
Thanks for any help.
P.S. I did purchase the FAS DPD chlorine test that's been recommended here online today. I should have that soon and will be able to get very accurate FC & TC results.
