Thanks guys. I am going to do 15g water changes every day until it starts coming down. I got my skimmer to begin working properly so that is a relief. Just clear bubbles so far but it won't be long I assume. Ham, thanks for the offer. I have a refract but it isn't as crisp with the results as yours. I may take you up on it but probably not today. I will let you know if I need it. Besides the scare, the tank and inhabitants look pretty good!
