Okay folks, here is another question. I started a 100 Gallon dirted tank with Organic Miracle Grow on Saturday (4/14/12). I transferred every resident from my 56 Gallon tank (fishes, RCSs, driftwoods, clay pots, 40 gallons of the of the 56 gallon water, plants and my CF-400 filter) and I was expecting an instant cycle. Well this morning (4/16/12) I saw one my Red Eye Tetras dead which I've had for over 2-3 + years and never had a dead fish in my 56 Gallon tank. I did a water test using the API Master Test Kit and check ammonia levels ( its hard to tell, but it doesn't look like the .25ppm color it looks more like 0ppm color but I'm not sure) Ammonia- 0ppm Nitrite- .25ppm Nitrate .10pmm is this a mini cycle? or cycling period? Help Freaking out here, I'm attached to my current residents of fish. I just ordered another canister filter CF-500. I was thinking of buying Tetra Safe Start and dumping the contents into the new filter when I get it or should i get it now and dump it in the tank? What do you think?
