Hey Alex! Sounds like we may have used the same pool store. Yes I am from Oklahoma as well. I have been using wipe out shock as well as crystal clear shock, did you have any problems when switching to BBB method. We are a new pool owners and not by any means chemists! We want to convert and have been using cooper based algaecide as well, and just not sure if this will create any problems. Of course the pool store does not advise this, but at this point I find we are putting a lot more money into it than we should have to. Any advise or comments you have would be great! Thanks-Michelle
