A picture is worth a thousand words . . .

Well, my 6:00 pm CL & PH are:

CL 6.0
PH 7.8

I am convinced that I still have algae or I don't think I'd be losing that much CL during the day - even on a sunny day. I took another picture of the steps tonight, after not brushing or vacuuming for a day so that you can see what has settled out on the top step and see how yellow the second step is, due to what has settled on it. How can algae still be alive and growing after all this chlorine??

I asked about this last week but didn't pursue it - but how do I know if I have a filtration problem? I am thinking that may be it. It really doesn't matter what I pour into this pool - NOTHING CHANGES!! I have put almost 85 gallons of Chlorine in the pool and in the past two weeks, 2 gallons of acid with almost no results. Tonight, my filter pressure guage is spasmodically hovering between 35-40 and it has always run steadily at 18-20. Even when I backwashed, it didn't change, so I don't know if that means the guage broke today or if this indicates something going on with the filter.

I am getting desperate for some answers!
