are you going to put the L46 with the L260?
Hypans can be aggressive with each other. now im not a stickler to the rules, but when you spend that sort of money on something you should leave no room for error.
now when you treat with furan II, don't make the mistake that most stores do; and complete the treatment like you would if you were on an antibiotic dose. do lots of water changes and seriously consider adding a cannister filter to the tank if you are adding L46 in there. They like moderate water flow and clean, good quality water which is easier achieved if you have a cannister filter.
