Extremely cloudy green water.

Your neighbor's probably smelling stuff comprising the 2ppm CC. The presence of CC indicates the FC in your pool is still doing work.
I'd definitely vaccuum the stuff that's already settled before using the floc/clarifier.

Should we use the GLB Drop N Vac now then?

You can use the PAC anytime you like -- I had to check, but high chlorine does not affect it. You might want to do a 5 gallon white bucket test of pool water and 1/8 teaspoon of the PAC mixed, and allowed to stand for 24 hours. (If the bottle is labeled for less than 20,000 gallons, use 1/4 teaspoon.) Flocculant behavior is not fully predictable, and even though PAC performance is more stable than alum, if you have time to test first, that's good.

Ok, we vacuumed yesterday without the drop n' vac, then we put the drop n vac in last night and vacuumed again today. Definitely making progress. There's a ton of algae being washed out. We're doing the same thing again today. We brushed the sides really well while the pump ran after putting the drop n vac in. We haven't re-tested anything but chlorine levels yet, but we'll do that after vacuuming again tomorrow. As of today our FC is 10.5, CC .5, and TC is 11. So it's dropped a lot in the last week or so. (from a TC level of 26) Here's the latest picture.



We can actually see the bottom now, but it's still pretty cloudy. I'm guessing the CYA is still high, so we'll test tomorrow after we vacuum and drain a bit more. Anything else i'm missing or are we on the right track now? Thanks a bunch for all the help. I'd still have a green, nasty pool without all of your help.

[PoolDoc]

Great!

Thanks everybody. The algae is gone! We've tested, and we're ready to fill up. Just want to double check a few things and see what needs added. Vacuuming to waste got rid of about 1 - 1.5 feet of water, and here are our latest results.

FC - 6.5
CC - .5
TC - 7
pH - 6.8 to 7. (Probably closer to 7)
Alk - 90
CYA - 48

I'd really like to raise the pH about .3 or so if possible, to be safe. I have baking soda and borax ready to go, just need to know what to add. Again, thanks for all the help, you guys rock.

[PoolDoc]

Add borax 1/2 box at a time.

Add it to the skimmer slowly while the pump is running, breaking up any clumps.
