I am a first time fish owner. Right now i have a 10 gallon tank with a power filter.I let the tank cycle natrualy for 4 days first.I heard that to help cycle the tank faster, and natrualy you could get hardy fish. So i looked on line and decided to get tiger barbs, neon tetras, and 1 cat fish. As i soon found out it was a big big mistake. Unfortinetly more than half the fish died. I did some more reserch and found out that you need to cycle the tank much longer. I felt so bad. I only have 1 barb, 3 neons and the cat fish left. I dont want any more of my fish to die and i heard that you could buy some bacterial supliment to instantly cycle the water. Has any one ever use it and dose it work well?
