So after using BBB for about 5 years and then granular stuff for a few years to avoid all those bleach bottles, we went to the local pool store and got talked into Bacquacil.
Haven't started it yet and became increasingly reluctant to do so after reading more about it on this forum.
Decided last night to try to sell the Bacquacil stuff and stick with the bleach. I feel so much better .
Using the granular stuff has left us with a high CYA of about 100 so that will take some time to come down I guess. What level should I keep the FC at to deal with this?
