I was thinking of 2, 1 black moor and 1 oranda both being between 2-3 inches. I have an urge to add 5 ghost shrimps and 1-2 snails. I have 2 HOB filters 1 is 125 gallons per hour and the other is 350 gph and also has bio filter, I also have a 48 inch bubble wall bubbler. So 475 gallons of filtration (more than x10 filtration) +bubbler. I would have to cycle my tank though. I beleive walmart sells amonia to begin my cycle. Would I need to add in the safe start to add fish even if I dont have fish or not needed? Also Do I need to get bacteria or will bacteria form on its own with the ammonia. Once the ammonia goes to 0 in 24 hours my tank is cycled right? So after would I have to do a 50% water change or 90%-100%?
