Well, to his credit, I think JakeH might have a point in that the tank MAY not have fully cycled? His manner might have been a bit uncouth, but I see his point. I remember reading through this thread but don't remember details on the filter. I also remember that the fish seemed to have been transferred as a group?
A new pond + fish dying = usually means a problem with the cycling especially if it is a start up cycle. Just because someone has the means and the will to build a 3k doesn't mean he knows everything about fish keeping. I know when I started my 1k pond, I knew practically nothing and learned a lot along the way.
Diego, perhaps it would be good for the community if you would give us an idea on why you think the fish died? What happened in that one week that you were away that led to them dying? I mean, if your household help overfed them leading to a spike in ammonia, a working filtration system should have taken cared of that, albeit getting it overworked a bit. If it was just the ray, it would be a no brainer that the water parameters might have been off. But for an aro to die, it seems more complicated OR that the parameters are thru the roof.
I also noted that when some of your fish died, you literally "cleaned" the tank?
Doesn't that make it worse since your tank will recycle again? Not unless there was a problem with parasites...
Also, your reply to that guy worries me also in that it is not the water or the chemicals or the aging water that we are all worried about, it is the stability of your nitrogen cycle and the robustness of your biological filtration. I've been keeping fish far longer than you brother and trust me, I'll be the first to admit, my knowledge is at best just a notch above a noob. Hehe
