Tiny Bubbles!

On the sides of my pool. Is that because I added 5.5 lb. of dry acid last night? Let me explain. No. Let me sum up:

Since filling with municipal water and chlorinating to open the season, my pH had been near-perfect while the TA was high, above 200 at times. Recently, after water level dropped and the pool outlet started aerating a lot while the kids were splashing around in the pool, the pH finally spiked around 8.0 (not really a very conclusive test using the little blue box in my TF-100 kit). So I had some pH Minus left over and decided to use it, attempting to lower my pH to 7.0 as others have recommended in an effort to lower the TA. I retested my pH this morning and it was 7.2. I did not bother trying to retest the TA, which was 250 before I added the dry acid.

So this afternoon, after ambient temps peaked around 91 and pool temp is 87, I'm swimming in my crystal-clear pool but see all of these little bubbles clinging to the wall of the pool. Is that due to the dry acid?

(I know, I know. I should be using muriatic acid, which i will look for in the future ;-))

Bubbles on the walls can be the first signs of algae. Any slickness to the pool at all?

With the Intex pool, I wouldn't worry about the TA anyway. It's not really going to cause much problem other than climbing pH. Keep the pH, CYA and chlorine in range and have fun.

Maaaybe a little slickness, I don't know. My chlorine last night was down to 1 and I added enough chlorine to get back to 6. I'll recheck the chlorine tonight after evening swimmers.

You'll probably want to do an overnight chlorine test to see if you lose any FC.

Just did and FC dropped 1.5 ppm (5.0->3.5) with .5 CC, which was not there last evening. I'm gonna vacuum in a little bit and add some chlorine in preparation for a pool-full of revelers later today!
