My tank is up and running at work. I needed to break down a tank at homeed and add some critters and live sand to the new work tank. I used old, dried rock from past tanks to aquascape the new tank.
Since I needed this work tank up and running quick, I ordered Bio-Spira to cycle the tank quickly. By reading the Bio-Spira reviews and instructions, I knew I needed to add inhabitants within a day or two to get a bio-load in the tank so the nitrifying bacteria the Bio-Spira introduced could survive.
Having said all that. the Bio-Spira didn't work as adverised and I've suffered significant loss. I got an immediate Ammonia spike - 0 Nitrites and acceptable Nitrates. I learned a lesson the hard way.
I'll keep everyone posted as things progress. I think today's survivors will make it but there will be no more additions until the levels are where they need to be.
My bottom line - don't trust Bio-Spira, don't trust quick fixes, don't trust product reviews. Just stick with the traditional tried and true methods.
