Welcome to the forum. As much as we'd like to help you, we're gonna need more information. Namely some reliable test results. Please visit Pool School on the home page and consider getting one of our recommended test kits. How are you testing now? How are you chlorinating?
No more floc for you!...(please)
Have you vacuumed up the floc? If so, hopefully you didn't vacuum to the filter while it was on circulate. It can goo up a filter and is one of the reasons we don't recommend it. Can you still vacuum any up?
FC 12 is our recommended Slam level for your CYA of 30. A point or two higher won't kill you.
Ok. You put in floc....nothing dropped out....floc is still in pool and could be most of your cloudy issue. Stay at it.
If you have been running your pump and filter Floc may have be in your sand filter messing it up. It is like glue, so check your sand filter. I made the dumb mistake of using Floc and had to through my filter cartridge away, it was hard and clogged.
