Big Water problem#1
Hi all
Had my 20 gallon tank running for 5 years with no issues, done a,water test yesterday and the ammonia was slightly high maybe because my nephew dropped to many small cory pellets in the tank I tried to get as much out as possible,
Done a 20% water change no joy the ammonia got worse and nitrites was high the water smelled odd .
Rang Maidenhead aquatics for advice, done a 50% water change using Seachem prime as usual no joy, brought some quick start and ammonia remover dosed the tank after a 50% water change but fish all at the top so not looking good no deaths yet I have the Fluval u3 filter a air stone .I have a betta 6 female swordtails two balloon mollies 7 corydoras shrimps and assassin snails haven't lost a fish in over a year
I'm at a lose what to do ,any advice would be appreciated
Kind regards
Peter
