I'll add that the alkalinity is at 70 ppm...and that I ordered a pressure gauge that should arrive by Thursday.

Re: Hello summer, hello algae, hello pool forum!
I don't know about the pH, you've got a lot of chemistry going in your pool and pH is difficult to predict. But, we do know how to measure it and how to adjust it. As you're near the bottom of your pH scale, you need to raise the pH with Borax. Half a box slowly in the skimmer with the pump running, let it mix a couple hours and measure it again. As you'll be dosing with dichlor, we can guess the pH will drop as the chlorine is consumed so let's aim for a relatively high pH - 7.6-7.8. Another reason for somewhat higher pH while getting rid of amonia is that the intermediate CCs may be less noxious at higher pH. But do try to keep it in range.
Re: Hello summer, hello algae, hello pool forum!
Well, I'm just now starting to get the FC to somewhat stay and my CC is dropping. I lost about 3 ppm FC last night and about the same since this morning. CC was 1 ppm each time. Also, I now have some CYA with the addition of the dichlor that I have used. I am to 40 ppm CYA. My pH is was continued to bounce a bit, as I didn't have any borax and have been too busy to run to the store for a few days (20 minute drive one way to get borax), but I have some now.
The water is still very cloudy and since this morning has had a white splotchy film on it. I can't quite tell if it is some sort of foam or not. Any ideas?

Anybody there?

Re: Hello summer, hello algae, hello pool forum!
Just keep the FC at shock level for your CYA level and run the pump 24/7 so that the filter can help clear the pool. Don't worry about the film/foam. It should dissipate as the water clears up. Shocking is a process, not a one-time event.
Re: Hello summer, hello algae, hello pool forum!
I'm not worried about the film. I would, however, like to know what is causing it. I don't just do things because someone says, I'd like them to make sense to me.Originally Posted by chem geek
I will surmize that one of the additives in the dichlor that I had been using caused it. Does anyone think that this is true or is there another answer?

Sorry I didn't see your post - Cub Scout Camporee, electronics are prohibited. Chem Geek is right, of course, stay the course, maintain shock level, brush, run the filter 24/7. Keep it up until you lose less than 1ppm FC overnight, have nearly 0ppm CC, and your water is clear. The keep FC at shock for one more day.
Re: Hello summer, hello algae, hello pool forum!
Someone with a similar situation in another thread was encouraged to turn their pump off to see if the cloudy water would disappear, as suspended particles fell to the bottom. Should I do this? If so, how long would the pump need to be off in order to tell if this is the problem? Also, I assume that I would still be keeping the chlorine at shock levels, I assume just by adding it to several spots in the pool.

Re: Hello summer, hello algae, hello pool forum!
Another thought...should I be operating at "shock" or "shock plus" levels? I originally started out with no cya, so a shock of 15 ppm was what I was using. Now, I have 45 ppm CYA and am running FC levels of around 18 ppm. Should I bump it up to over 30?
