too much flocculant or bad filter?

[matt4x4]

I'll take an educated guess here and say it's too much stuff to close together, From what I can tell, you added shock, algaecide and floculant.
A cloudy blue pool is fine, it means that at least the algae is DEAD, however, the pool usually becomes cloudy from the dead algae, since algae is very fine, floculant helps speed up the process of settling it and filtering it out.
Algaecide (although the name implies it) is not very effective as an algae killer, more effective as an algae preventer.
It is recommended that if you want to use it, add it in small doses regularly to a clean pool, not in the large dose recommended for killing algae (I think they put that on there so you go through more product) - it actually foams your pool and doesn't do much else at higher concentrations, this mixed with floculant is probably what caused the issue.
Floculant should be added when you see that the algae is dead, circulate for about 8 hours, then let the stuff settle with the pump off, you should see a fuzzy layer of filth on the bottom, vac this up MANUALLY - very slowly - an auto vac tends to break it up and blow it around, and you just have to let it settle again.

when using floc it's IMPORTANT that you let the stuff settle, then vacuum to WASTE, and slowly, so to not stir it up into suspension. Do not vacuum to the filter. If you have a sand filter, and the dead stuff is too fine it'll just land up blowing it back out the return and give you a cloud. As far as the white buildup, im a chlorine user, so i'm not sure what thats all about, maybe some chemical reaction to your sanitizer. There may be a specialized floc for your type of sanitizer thats different than the one for chlorine pools. Hope this helps......
