i'm setting up my 120ga tank. I used a bag of live sand, and lots of crushed coral, and had a tone of base rock. I added a few pieces of live rock from my smaller marine tank. I stole some filter media from my established tank, and also took some substrate from my cycled tank and put it in a baggy and stuck it in another filter. I did a partial water change from the established tank and put it in the new tank. I went out and got 4 damsels to do the rest of the work for me.
last night i noticed one of the damsels was not a good color of blue, but he was eating aggressively, so i turned out the light and went to bed. This morning he was no where to be found. I tore every piece of rock out of the tank looking for his dead body and finally found him stuck to the power head. Part of me wanted to leave him in there to speed up the process, but common sense prevailed, and i took him out, and did a small water change (7g)
I tested the water and got some numbers:
I understand in tanks with high ph
, ammonia is much more toxic, and there fore this amount of ammonia could be a problem
my question is, are these conditions to blame for the death of my damsel? I know these guys are really hardy, and as someone has put it to me "can live in rootbeer" haha, or do you think that my power head is to blame? I really cant see a healthy fish getting stuck to the powerhead, but these are small lil buggers, so who knows?
finally, i was wondering if anyone had any advice on anything i might be missing in regards to cycling my tank? Have the measures i took to speed up the process reasonable, or a complete waste of my time? Anything that might speed up the process?
