and run carbon (changed frequently for the first few days) and then weekly after that. The intoduction of a good liquid marine vitamin high in stabalized vitamin C will be plus. Best dosed between carbon changes as it will pull it out some.
Watch for animals possibley causing it irritation as well as nearby corals. Be sure the torch itself is not against any hard surfaces as it will cause necrotic tissue as will sustained heavy water flow.
