Dead Algae on pool floor-vacuuming??

[Guest]

I have spots on the bottom of our pool that looks like sand. But when you brush them away, it just disapears into a cloud.

So I've tried vacuuming this up, and then after awhile it reappears.

the pool store told me it was dead algae and to vacuum to waste. I did this but its back again this morning. Although when I vacuumed I didn't get to vacuum all of it.

I used to have this problem a lot with my old pool. I had to add a liquid that would coagulate the dead algea so the filter could pick it up. So, I would pore that in and use a brush (with a long handle) to kick up the dust (to mix it) and run the filter. The coagulant can be bought at any pool store.

This liquid is known as "Floc" or "Clarifier".
