Is it okay to cycle with fish using Colony?
Yes it is okay to introduce fish with Colony in the aquarium. Because the instructions of Colony keep feeding to an extreme minimum, ammonia and nitrite spikes are very small and short in duration. What ultimately makes this efficient is that the true nitrifying bacteria in Colony will come along faster with small amounts of ammonia than huge amounts. Too often Colony is “tested” rather than “used”. Therefore, throwing the kitchen sink at it is impractical and counterproductive to the organism and the cycling of the aquarium.
In short, little food leads to little spikes, leads to faster cycle.
