Shock green swamp

Do you have a good test kit?? If so what are your current numbers? For us to answer that question would be like answering "how far is it to New York?" We have no way of knowing just how far you have to go to get there at all.
 
You may need to add bleach every hour to maintain a high enough FC level to kill the algae faster than it can reproduce. How high that level is depends on the CYA level.

If you don't have the proper test kit, you're wasting a lot of time and a lot of bleach.

Start reading pool-school/ to gain an understanding of what I just wrote :wink:

It CAN be done. Here's a recent thread with some before and after pictures that should inspire you
 
Sorry,I haven't had a green pool since last year and I am rusty. I put 6 lbs of cya in yesterday. My FC is 12.5 right now. Put 3 gal.bleach 1 hour ago. My cc is .5.

My cya was zero yesterday so can't test that yet since I just put some in.
