high nitrates rarely kill fish . are there any women that use sprays etc near tank ? what do they use to clean the glass ?
Single guy with a 12yr old reef tank sitting in the same room, no problems with the reef tank so sprays etc are not likely
most fish have been starved for weeks before they reach the lfs so they are weak and will be subseptable to disease .
Last batch of fish we made sure were fed properly, not the problem.
i would first run excess carbon for the possibilities of sprays etc .
They are running carbon passively, they are ordering a dual reactor we will fill with carbon this week.
then all fish in the tank need to be treated in the tank for bacterial and fungal infections .
They have treated this tank and inhabitants several times, the last time was with copper
what is going on with the ph ? are there large swings ,check and see .
Haven't checked ph.
many fear electrical current but the fish have more resistance so that wont even effect them but you can check for stray voltage .
They didn't have any equipment to check for voltage and I didn't take mine over there but if there is current it's not enough for a human to feel it.
the disease controll seems to be what you need to get a hold of . are the fish all coming from the same store ? that also could be an issue . are they very delicate fish ,if so try a hardy fish that is tank raised and see what happens.
what is being done to properly acclimate the new fish ?
1 hr gradual acclimation.
copper residue may not be high enough to effect the inverts but that also wouldnt hurt the fish . what is the salinity of the lfs water ?
1.22, same as the tank.
you really need to leave the fish in the tank and treat for disease first and then get all the pperamiters correct then add a very hardy fish and see what happens . how may new fish have died in this tank over how long of time ?
Tank has been running a year, they have lost aprox 50 fish of all kinds.
if you post an answer to most of my random questions that may give us some vital information to go on . also how long has the tank been up and running and has it cycled properly ? check for temp swings ,and could there be any hitch hikers that may be harrasing the newbies . many times you can find clues of preditors earl in the morning in the sandbed but the golby probably disturbes the paths they may make so it may be difficult to see .
No sign of any predator. The fish all do well for 2-3 weeks and then they die. Usually they get a bit lethargic the day before. Only Foxface shows white blotches and cloudy eyes before dying. One thing I noticed is this is a large tank, 240 or 280 gallons and even though he has a sump and a built in corner overflow the water in the tank moves very very little, with lots of particles sitting on the top of the water. I'm wondering if at least part of the issue might be a lack of dissolved oxygen. We added a couple of Koralia 4's he had and installed them so that there is water movement across the top of the tank. I kind of doubt this is it but can't hurt. Oddly enough of the fish that haven't died in this last round there are three anthias, in my experience anthias are not very hardy.
