Ok so here's how things are developing:
Vader has eaten
despite having to live in a breeding chamber at the moment he has still eaten some artemia. (I bought a frozen pack as that was what he was being successfully fed at the lfs)
I also bought him some betta food but I can't find the tub now to let you know the name
In terms of the ammonia I thought I would see how things developed after my 90% water change, and to be honest it's pretty much sitting between 0.5-1.00ppm. What has happened I am still completely baffled with myself. Whether I have any live bacteria in there is questionable.............
However: A big shout out goes to: TRIMAR AQUARIA in Camborne, they have been brilliant, firstly offering to loan me a light unit when mine didnt work and my plants needed light, and secondly bless them they have given me some mature media
Soooo I have placed the ceramics they have given me into my tank, gave them some in replacement and put what they have given me amongst another bag which has been in there all along.
I guess now its just a waiting game.
Meanwhile, Vader appears to be doing well in his breeding chamber in my 54litre - I am replenishing his water daily just in case he may get a build up of ammonia in there. (I know some say they don't often get a very good flow in these)
I shall take another ammonia reading later on tonight to see if any change in the parameters
