My Nitrite is 0
Nitrate is 40
I cant test for ammonia
clean every 2-3 weeks with 50/60% water change
its a 61 litre ran with sponge filter
I have rumynose/cardinal/neon/ember tetras with 5 sterbai Corydora and 3 barbs
I treated my tank yesterday with API PIMAFIX for fungal infection. Today my fish seem sluggish and dopey and my ember tetras are breathing quite rapidly and staying low on the substrate. this is 1/7 daily treatments is this normal ?
my results were:
NO3-40ppm
NO2-0ppm
pH-6-6.5
KH-0ppm
GH-30ppm
I last cleaned and completed a water change 2 days ago (50%)
Any feedback on how to improve water quality?
