Our pool woudl not hold FC and the CYA was 250-300.
We drained the pool about 80%. we have a 20,000 gal, gunite pool.
We started refilling and noticed a greenish color. We have since tested and the pool with a K2006 kit.
FC - 0-.5
CYA< 30 (the black dot was still barely visible when filled to the top of the test tube)
We added clorax bleach at the recommended rate per pool calculator. 2 hours later , no FC.
We then shocked it with Hypo chlorite in the evening, in the morning no FC - however the pool is now very clear.
We have some left over dichlor tabs in the cylinder that we are using to raise the CYA slowly. However we need to get chlorine back in the pool. Can you please give me some suggestions. Should we add stabilizer, or just keep adding bleach until it stays?
