Bio-Spyra cycling

Agreed. You can do a fishless cycle with bio spira, and adding ammonia.

Not sure what the point would be, other than some unexplainable delay in adding fish right away as the manufacturer recommends.
 
The point would be if anything goes wrong with your Bio-spira, before or after it is added, you don't have the work and hassle of a high bio-load fishy cycle.
Ideally adding the bio spira, dosing ammonia and testing would give you a tank ready for full bio-load within a few short days.

If you add the fish and bio-spira and the bio-spira is dead or dies, look at where that leaves you. It isn't impossible to deal with but it is very high workload, and creates emergencies that are otherwise unnecessary.

I use the same system when seeding bacteria from other tanks, Add bacteria and ammonia test for result and if it's good add fish, if it isn't I have no emergency on my hands just a slight delay in the process.
 
Sounds reasonable. Just not sure how probable it is for experienced aquarist. I can see how it might be a better recommendation for a newbie by the manufacturer. How ever, it seems better not to run the expense for a newbie and just do a fishless with ammonia. Wonder what the "failure" rate is for bio-spira? Anybody have a guess?
 
Well, its been a few days and my water parameters are still the same as before: ammonia, nitrate, nitrite all at zero. I've done a 35% water change, My betta is looking good and has a healthy appetite; over the past week I've lost three rasboras out of the ten I originally brought home. The rest look fine, with good appetites. Chickiepooh was right; I should have waited to put the betta in last of all. I have that nauseating feeling that only a newbie knows when a needless mistake has been made. However, my bioload of fish is currently very small, and I must add more, especially bottom cleanup fish, but I will first put them a little at a time in my 5 gallon hex for a few weeks before adding to the big tank. I don't know if my tank is cycled after all, since I never had any measurable readings. My melted Crypts are starting to grow back and I'm dosing excel every other day. Thanks for all comments and advice.

It's hard to take a guess at it, But we see a lot of folks on the boards who do have failures. It almost always goes back to poor handling, so it seems to be location specific in a lot of cases. Too many LFS, and shippers do not handle the stuff properly. In the case of those who do failures are pretty rare.
