My 55 has been setup for about 4 weeks now. When I first set it up I added beneficial bacteria to help it get started and I also seeded it with my canister filter from my 46 bowfront. I've been putting in fish food every other day to produce some ammonia for the bacteria and the ammonia test is coming out at 0 ppm. It did get really cloudy for a day but I've read that that means it has cycled. The thing is. The stocking is going to be shell dwellers and I've been told to add them all in at the same time because they're quite territorial and if I don't it might be like a "home court advantage" but I don't want to cause a ammonia spike. Do you guys think if I add them all at the same time it will cause a spike even with the tank size and a cascade 1000 canister filter (rated for 100 gallons)?? Also I'm only adding 8 Multis so a really small fish to this and hoping to start a large colony. Please respond, the fish are getting ordered tomorrow. Thank you!
