I have a 40,000 gallon pool. When I opened it this year it is green like a swamp. I just joined this forum and I am impressed by how helpful everybody is.
I want to start shocking my pool. I District the Walker today I tested the water today and the
CYA is 0
I need to shock the pool. My question is should I use liquid chlorine or dichloro? I am thinking of starting with dichloro as that will increase the CYA levels also. The chlorox brand dichloro I bought states it has 58% dichloro. Based on pool calculator, if the calculator tells me to use 10 lbs of dichloro do I need to increase it to compensate for the fact that my dichloro is only 58% active per lb....does that mean I need to add 4 extra lbs to compensate for the fact that my shock bags contain only 58% dichloro per bag?
