Special Blend is Microbe-Lift's version of Seachem Stability. It helps control ammonia, breaks up sludge, unclogs filters and sets up a decent biofilm for the nitrifying bacteria to colonize. But, like Stability, it does not contain the actual nitrifying bacteria that performs the nitrogen cycle. It just prepares the way.
Microbe-Lift's Nite-Out II contains those nitrifying bacteria. So does Tetra Safestart, and API Quickstart, ATM Colony, Dr Tim's One-and-Only and others (nitrosomonas and nitrospira are the magic ingredients). These live-bacteria products work fine as long as they haven't been frozen, over-heated or left on the shelf more than 6-months.
You don't need starter fish. Just stock about half what you're planning. Then shake the shake out of it and pour in the whole bottle the next day. Monitor daily and be prepared to do a large water change (just in case).
To play off of Flint's suggestion, you can use it for a fast fishless cycle by using "pure" ammonium hydroxide as your ammonia source. Keepers I know have successfully cycled their tanks in 5 to 10 days with TSS, Quickstart, and NO II. As long as two weeks with Dr. Tim's.
If you go this route, please log your progress and tell me all about it. I track this stuff. Thanks
