"Nothing GOOD ever happens fast in a saltwater aquarium"
This is a quote from a saltwater hobbists I picked up over the last few years. I can tell you who I got if from but I think they got it from someone else so I dont know who coined the phrase first.
But I have to say its very true. If it happens quick its probably not a good thing.
If you get some cured live rock you can speed things up to some degree also.
A good cycle is the basic foundation of your tanks health. A speedy cycle that is rushed could lead to health problems down the road a few months.
