I would try bleach or vinegar or maybe even a mild disinfectant called Milton or equivalent. It's used to disinfect babies bottles. The ratio, i'm not sure. Maybe someone can come in with that. I'm sure one or all of those would work. Make sure you also do everything else too, filters, heaters, decor, substrate etc etc. Afterwards, give a really good wash/rinse in WARM water, please NEVER, EVER use hot or boiling water. I learned that the hard way, lost a 55g!!!!
