just bad luck???????????????

No nitrates? Did you just do a water change or something? Are you feeding them? (Just kidding). What was the tank used for before this? Sometimes if a tank was used for FW and then converted some of the FW chemicals can leave a residue in the tank.

Percs are pretty hardy. Weird that one would die without warning like that.

To your answer there is a minumal water flow in your tank you need to have more water flow, I see that you have cyanobacterial build up in the sand bed which is the first reason and second is that the filters you have are not for salt they are for fresh, this in terms tells me that you have high beds of phosphates and nitrates . You did say that 0 nitrates the test may or may not be true. Are you using an R/O or D/I water? The other thing is that this is a new tank and may have been pushed to the edge. It's called new tank syndrome and will eventually take a bigger toll if not corrected. Can you please give me a full detail on your setup? The more that you can tell me the more of a full recovery will happen.

It can process 200 gph, however for the live rock to work as a filter they must have flow running over them. The HOB filters only take water out of the tank and put water in. It doesn't provide any current for the bacteria on the rocks. Thus, no biological breakdown because there's two new filters in there and the live rock isn't getting current. The one powerhead I see in there doesn't look powerful enough, plus it isn't providing flow over the rocks.

This might not necessarily be why your fish died, however you must have current flowing over the live rock in order for them to work as a biological filter. Also, if you have two filters and want to change them out you should do one at a time. If you had any beneficial bacteria within the filters it's gone now unless you kept the filter media.

You don't necessarily need filters - just a protein skimmer, live rock, and plenty of flow, though I use filters on my tanks.

I would suggest that no more fish be bought till you have corrected the water flow problem. You need at minumal 10 times the amount of the tank in water flow per hour i would suggest a higher rate like 20 times for this to clear up and also the tank is very new and will take another 3-6 months for the problem to clear up completely and your water from the last test looks fine but like I said it is too new for heavy loads of live stock to sustain the bio load that is needed. If you add more stock at this time then you will end up loosing just about everything and that is not a good thing. So please slow WAYYYY DOWN and things will turn around accordingly!!! you should have a total water flow with a sump not HOB and with power heads or I prefer propellar type heads that give a wider water flow than the traditional power heads that shoot a straight stream of water. Look into Tunze or Koralias for this pump. And do get the proper protein skimmer (foam fractionator) preferable a venturi type and not an air driven type. this will eleimanate all the bad bacterias and also the algeas that are not needed for a enclosed system. With out this type equipment you will be fighting this tank till it drives you crazy and you will loose interest in the hobby.
