Thank you Radley for your reply, I am gonna wait for the ammonia to reach zero first, I am trying very hard to hold off on the water change until the cycle is complete. I have a blue throat male teenager trigger, three pec clowns, one six line juv wrasse, one blue spotted jawfish, one bi-color bleeny, one orange-spotted goby and four yellow tail "hellion "damsels. I also had a yellow headed clown goby which I think is causing the ammonia spike as I believe it's dead because I haven't seen it since the first day I put it in the tank and the damsels chased it. I have a 215g sw with 4" of deep live sand, my sump is a pro clear 300 with duel built-in overfolow boxes and a 36watt uv turbo twist 12x sterilizer hooked up to my magnetic drive 2400gph pump. I use a 950gph magnetic pump also on a etss 500 skimmer. I only use a white poly floss on top of my double box of bio-balls that I change every week. I also have a canister with some carbon media and some other kind of media like puri-cure in it which just cycles the sump independently. Long story short, I had a 30g tank that crashed because the canister filter went dead so instead of just buying another one I put the fish in my big tank with the damsels, all are healthy without disease as I have had them for awhile so I figured what the heck. Then I ended up buying another canister filter anyways sooooo, I should of just waited to add the fish butttttttt to late now.
I do plan on later buying this summer a male anthia with five or six females and then later after that two female blue throats to complete my tank in the end. I don't know if I will keep the damsels or not, my tank is pretty big and gurthy wide so I might just elect to keep them. I will buy another canister for my smaller tank and have it set up as a qt tank for the anthias and triggers later for sure before putting them in the main tank.
