 fresh water nitrites
my mom has a 20gal fresh water tank with 2 med angels 6 zebra danio and 2 gourami's and i know she has a few live plants in there also she said everything looks healthy but she tested the water yesterday and her nitrites were high so she did a 50% water change yesterday and tested this morning and nitrites were still high... i told her i thought the tank was kinda overloaded but what can she do to get the nitrites down?
thanks |
