02vetteboy - In my opinion your lfs done you good! A lot of folks may not agree with me but I love Bio-Spira! I've used it in both FW and SW with excellent results. When I set up my RSM I paid a premium price for fully cured rock, with a lot of life still on it, and I added some Bio-Spira with my rock, and again about 2 days later with a few fish. I never had a measurable cycle - never had any ammonia or nitrite, just some nitrates. And I was testing with 3 different test kits to be sure. Same thing happened when I set up a small 9g SW tank - no measurable cycle. Bio-Spira is actually from Marineland, and it does what it says for me - in both FW and SW. Not cheap as it's refrigerated live bacteria, scientifically developed to have the correct types of SW bacteria to handle the nitrogen cycle. If I sound like a Bio-Spira commercial, I'm sorry! Some of my friends have tried it also and had excellent results. Even with rock not fully cured it has definitely shortened cycles. Maybe Instant Ocean bought the rights to Bio-Spira? I've never had any decent results with the unrefrigerated or store shelf cycling products, and I think I tried them all back in my FW days, before I tried the Bio-Spira. You won't see it sold in a lot of lfs, because it requires refrigeration and has an expiration date. I think a lot of people that have tried it with poor success have gotten material that wasn't properly refrigerated, or had expired. BUT, track your cycle to be sure - better safe than sorry, and don't add any more fish till the bacteria population has had time to grow.
