please help me

I would really say you have you tank WAY over populated even in a fresh water tank.
and the tank is only 2 weeks old , im assuming you have a plenum / and some gravel/rock or somthing in there.

Vut the amonia build up is coming from all those fish pissing i would say really .
( pardon my word )

 

what should i do wild, yes got gravel

 

you can buy some product that gets rid of ammonia, you can find it at any pet store. That is the quick fix. The ammonia is probably coming from having too many fish in that size tank. If you can, try to take some out or return or trade some in to the fish store. When everything settles down, then see where the ammonia level is at. You will need to do some research on stocking guidelines to get the appropriate number of fish

 

such as 'ammonia lock"

 

do i change some of the water will that help

 

yes, that is a very good idea, don't know why i didn't think of that

 

what size filter do you have? i would reccomend running some carbon

 

guitarman im really new to this how much of the water will i change

 

try to do a 25% water change, of the total volume, 180 liters. If that is too much, then do several smaller water changes over the next couple of days

 

thank you guitarman
