I haven't heard that.
I know CYCLE by Hagens is being reformulated (hopefully it'll actually WORK now) and that will be released in the fall/winter.
Seachem also has a product called Stability that works like Biospira but not as quickly that can survive at room temp.
I couldn't find the manufacturers web site for Biospira though but I would check there to verify it before buying warm biospira.
