The things that have been in both tanks are my arms, the python ,the filter cleaning brushes, and the magnet cleaner...sigh, I know. The only thing I can say in my defense is that EVERYBODY was FINE until I came down Wed. morning. I was going to use the Maracyn-One and -Two, but the disease site I looked at said triple sulfa for flex...'whinning' now what do I do?
