Starting a cycle

[Grayout]

I've always preferred the method of using an abundance of live rock and seeding the tank with the detritus/aged seawater pulled from another tank. My current tank was quickly cycled by using the live sand/rock/water from a pico that had been running for a year or so. I provided the tank with a small amount of ammonia by adding mysid a few times a week. Obviously, it's something that shouldn't be rushed as I'm still waiting for my DSB to mature and chaeto to grow out in order to feel more comfortable about the biological portion of the system. I'm a big believer in biological diversity within a reef tank.

I downsized from a 90G to a RSM250 65g I used 60% old water from the 90G and 40%new water, all the rock that went into the RSM came out of the 90g sand was all rinsed with used salt water from the 90g. the bio in 2 bags were from my 50g sump which ran with my 90g and is hydrton balls, lr rubble and bio rings.
Basically it was a big water change and worked great for me without any cycle.
