follow the instructions on the bottle or just mix it with water in a bucked and cast it evenly around the pool
You want to have the equipment running while adding any chemicals. You will want to wait about an hour after adding algaecide.
I suggest you contact the manufacturer of the algaecide and find out from them what would be the bes coarse of action.
Vaccum the algaecide and its treated remainder to WASTE. Keep testing until it is ok. It should be fine. You may also call the company who makes the algaecide to get their suggestions. When I had a problem with my pool about three weeks ago, the pool company put a LOT of algaecide in the pool and then I vaccumed it to waste. Now I put just the minimum in each week to prevent algae from growing.
a week because the fish can die if you don't leave it long enough
An algaecide (or algicide) is a substance which kills or inhibits the growth of algae.
You don't have to mix the algaecide in a bucket of water, you can put it directly in the pool. I use Polyquat 60 that comes in quart bottles and add about 4-6 ounces per week. Just walk along the edge of the pool and pour it at the edge while walking. No algaecide will "eat the paint". It's not acid. In fact, all the algaecide does is strip the cell walls of the algae and make it more susceptible to the chlorine. It's the chlorine that kills the algae. However, one algaecide with a side effect of staining is Copper. It's a very effective algaecide, and it's safe - but it will stain concrete pools if it's used in a high enough concentration. And Copper can stain blonde hair as well. That's why I don't recommend using it. The preferred algaecide is Polyquat 60.
Assuming that your pool is 24 Round 52" Walls, Roughly 14,435 Gallons. Amount to be used will vary depending on the algaecide used. We normally recommend refering to the label of the algaecide you are using. We use Blue Wave Halt50 Algaecide with our winter closing chemical packages which recommends using 5oz per 10,000 gallons for booster dose.
