Tank too clean ? #1
Hi, I have had my 100L tropical tank for about 17 months now. I have 21 fish , the largest being 4 small barbs. tempreture is between 24-25 c. My local aquarium centre checked my water tests & everything was ok, apart from very slight ammonia level.
The tank has run very smoothly , with no problems until now !
when i clean the filter out ( in tank water } there is hardly anything in it. The ammonia levels keep going up, i am doing a quarter water change every week now.
I have real plants in the tank. theres hardly any residue in the substrate & i am very careful not to over feed the fish.
So my problems are.... why is there no residue in the filter & why does the ammonia level keep going up ?

Re: Tank too clean ? #2
Hello
What kind of filtration are you using?

It sounds like you somehow crashed the bacteria colony. Best bet is to find some established filter media to kick start again. Or i have found thr probidio product (biodigest + biotrace) are very useful for jump start.
