| I was under the impression that if you have all LR and LS all the needed bacteria are already there...therefore there is no need to cycle. If I'm mistaken I guess additional dosing of Bio-Spira for saltwater should help. I've used the freshwater version of Bio-Spira on freshwater tank and it shortens the cycle considerably. My experiment was on a 12G tank. Without Bio-Spira or any "old" material from another existing tank, the cycle took about 4 weeks with fish. If I add Bio-Spira to an tank with new decoration and substrate, it only too about a week. |
