Need help !!
Ok firstly hello all, this is my first post. I don't usually post on forums just read, but I fear my tank is dying and I am kinda desperate for some knowledge and input from some peoples who's wisdom is much greater than my own.
Ok here it goes......
I had a 100L planted tank running a low tech co2 system for about a year, it's spent about 3 years as a unplanted tank so it's well established. I decided to go up a size ( or two hehe) and went for the Roma 240 by fluval, got it 20 days ago today sent it up and put about 100L of fresh water in the tank, treated the water with the API stress zyme and API stress coat, started the heater up and dropped a air stone or two in to help circulate the water. Left the water for aprox 3 hours then washed one part of my filter media in the new tank ( API buffer floss) an put a new 15 pound filter I'd bought in just to help the fresh water along a bit. I then started emptying the wood, rocks, plants ect into a quarantine tank, did the same with the fish (seperate tank from decor) I then put the sand/substrate into jugs. Removed filter and air pump and then I cooked and ate. From when I first put water in the tank to adding my old water was about ten hours so my first question is did I kill my Eco system??( I didn't add the last 40/50L for another 3 days)
Secondly, since going in my new tank, my pandas barely move apart from feeding time, and Iv had two lemon tetras die in four days( I can't remember the last time I lost a fish before that) and one of my whiptails has lost most of its colour :'( there's more golden sand in the tank now an I'm hoping some one will say he's trying to blend in with his background?? But the other hasn't??
Basically I'm tearing my hear out thinking my tank is about to die an I don't know what to do :s
All the normal water parameters have stayed the same, I was cautious from the start I might have a NH3/4 no2/3 spikes, no change at all, no change in ph, no new fish.
Can any one give me any ideas???
Many thanks in advance
