Ok, in that case I'd do what I posted above--try running it in recirc mode while you're still shocking, and when you're finished, leave the chlorine high but turn it off and see if it will settle where you can vacuum it. Once that's done and you're able to turn the filter back on, it should finish taking care of the "film" if it's not gone already.
Re: Hello summer, hello algae, hello pool forum!
Why are some people (with similar situations) being told to turn their pumps off and others told to keep them running?

Re: Hello summer, hello algae, hello pool forum!
Our general advice has always been to keep the pump/filter running so that the chlorine will kill off the algae and allow the filter to catch it, and that seems to have always worked in the past. However...this year in particular there are so many more people with cloudy water conditions that won't clear up than we've ever had, and pools that are not responding to the methods that have always worked before. We're not sure why, but we're thinking it had to do with the overabundance of algae this year, probably partly due to the warmer winter we've had. Ben is working on a theory that, in some cases, the algae is being pushed through the filter media, thus breaking it into even smaller particles that the filter then can't catch. This can happen with oversized pumps, undersized filters, DE or cart filters with live algae, or even some sand filters in pools overloaded with dead algae, as well as pools where the owners have put assorted "goop" into their pool before coming here in an effort to solve their problems. Some of that "goop" doesn't work so well with filtering. So...the advice we're giving now is sort of more dependent on each person's equipment and situation, rather than a blanket one-size-fits-all situation.
Re: Hello summer, hello algae, hello pool forum!
Several posters here this year have been unable to clear cloudy pools after killing all the algae and getting rid of CC. Oversized pumps with undersized sand filters is common to many of these pools. Ben has surmised that these pumps may be pushing dead algae through the sand filter and back to the pool, grinding the dead algae into particles too small to filter. "Let it settle and vacuum to waste" is an attempt to clear these minute particles.
Would you please give us (I can't find them if you have) pump and motor model number and filter make and model.
In the meantime, keep your FC above 15 (18 is fine) and brush the pool regularly until you lose less than 1ppm FC overnight and have no (or nearly no) CC.
You can move the filter to recirc if you want. Did you get the guage? Has your pressure been rising?

Re: Hello summer, hello algae, hello pool forum!
I did get a new gauge. The pressure has only risen a little bit. I'm still not to the point of only losing 1 ppm FC overnight and my CC is usually 1 ppm, too.
I'll look for the model information that you requested.

Re: Hello summer, hello algae, hello pool forum!
I am running low on POP. I'm not sure where you can buy that!
To amuse myself, and because I am a science teacher, I'm running two experiments. In the first, I have a clear glass of pool water and am simply letting it sit to see if anything settles out of it. In the second experiment, I have another glass of clear pool water, but have added a tsp of dichlor.
I don't know if I'll see anything happen and if it does will mean anything, but I've just got to do something besides add bleach, test, brush and vaccuum.

Re: Hello summer, hello algae, hello pool forum!
Things MIGHT be turning my way. My CC level is staying at 0.5 ppm or zero. My chlorine loss overnight is declining (only about 4 ppm last night). Then, today when I backwashed the filter, I noticed quite a bit of white...something being pushed out. Is that what the dead algae would look like?
Also, from my experiments last night, the glass with the dichlor added is almost clear, while the one that I didn't put anything in looks the same cloudy/hazy as before.
