Ammonia should be zero ( how long are dying animals staying in your tank?) Look for that yellow tail damsel. That ammonia number says it's in there somewhere decaying. Get him out of there asap. - I've been looking for him but there is just no sign of him. I've moved most of my rock work and no dice. I'll go back in and se if I can find him
SG is low (should be closer to 1.026)
Change out more than 5g at at time. You should be changing 10 - 20% each month. _ I do 5g a week, so 20g a month
You have a high bio load and you're feeding quite a lot. - I dont feed all of that, I mix it up daily.
Make sure you have a lot of surface water movement. How slow is your turnover? - not too sure on the turn over maybe 1-2x. I am hoping to have the last of my peices to fix that this set of days off. I have lots of surface movement, but I'll try and point one of the k3 from the bottom to the top.
What are your calcium, magnesium and alk numbers like? - I dont have a test kit for these yet.
Which salt are you using? - IO
What is your regular maintenance schedule? - weekley 5g water change, befor and after each shift. Cleaning during that time.
Do you have any sand and are you cleaning it regularly? - Approx 1" unless the fish/pistol move it, but then I level it out.
Are you running any carbon? - I did but the tangs got more stressed out from it. They were always hiding, I set it up again to to see if it helps.

(not that it matters, but Calgary still has fluoride, it will take probably a year before they stop adding it)

I use tectra-d for a coral dip, I don't have any way of quarentine corals so I did them and in they go. I do a fresh water for the fish. I use to quartine but I was loosing more of them then I liked too. Sinse adding them after a fresh water dip they seem to do much better. Havent lost a fish till this happened...

Everthing in the tank looks good during the day all the coral is out and in full bloom . The fish are all out and swimming looking happy, and they all eat like pigs when I feed them. I think if the fish were all stressed out the would all be showing sign of it. There is ICK in the tank thanks to one of the tangs but no one has it at the monent.

I'll try and reposition a power head from the bottom of the tank to point more at the top, I don't think there is much areas of low flow in the tank as I got one of the K3 pointing at the back of all the rock work.

Thanks

can you describeyour freshwater dip process for new fish?
