I suggest a 30% water change every other day for a week... or until the stats get to a good level..... and hope your fish make it... 160 for nitrates!?! wow...
my fish are still swimming, they like the water slightly acidic, and the nitrate doesnt directly harm them unless its been high for a long time, wich it hasnt
cool
nice tetra, i had 2 of em b4 in a smaller tank, some parasite came in that go into there scale, killed it, sukd the blood, u could see the poor fishes vains i guess they were, and the fins were all spikey looking, was so sad, bloodshot eyes, gruesome
