Residue on Polaris

[charsand]

I had to take my Polaris out of the water and left it out for a few days. There was a gray residue over most of it. I am currently in day 9 of shocking for algae. Is this residue algae related? It doesn't come off easily. It requires brushing.
Thanks

Full set of test results please?

It could be scaling.

Here are the latest test results:

FC 11.5
CC 0.5
TA 100
CYA 20
PH 7.5
CH 110

I have ordered calcium chloride and will add once I clear up the algae. I will also add more CYA later today.

I have been adding bleach about 5 - 6 times per day to get FC to 14....also brushing each time I add...
The pool has gone from emerald green on 6/5/13 to a murky teal, I can now see the bottom of the whole pool....I intend to change filters either today or tomorrow....this is going much better than last year

With those numbers it's probably not scaling. I'd just clean it up and not worry about it unless it comes back under normal FC levels.

OK...thanks....

Just one more quick question....since it takes me about an hour to an hour and a half ( I am slow and the body just doesn't function as well as it once did :-D :-D ) to change out my filters, should I do this in the evening, or is it okay to do it anytime.....I don't want to backslide on this algae battle....

Thanks

You should only be doing it when the pressure rises 25% above normal clean pressure. which filter do you have? It really doesn't matter what time of day (or night) you clean it.

I have the Jandy CV 460(cartridge)....the only reason I asked about the timing of the replacement is because of the possible bad effects of the sun on my FC level while I am battling the algae....
Thanks

As long as the pump ran for about 30 minutes after the bleach addition shutting it down for a couple of hours won't make much difference.

Thanks, that's what I needed to know....
