if you got gravel it could be it is loaded with organic material.
bare bottom tanks with 10 gallons per GF and using high quality food fed in small
amounts only need to do partial water changes to keep nitrates 20 ppm or lower .
as long as your tap water doesnt have nitrates.
veggie filters are wonderful for removing nitrates. actually, so is string algae.
my mom had a 20 gallon and she did like a quart of water change once a week but it
was loaded with string algae and the fish did fine for nearly a year. Ingrid

I would like to know what other ways are there to lower the nitrate
levels in a fish tank other then water changes. I can never seem to
get my nitrate levels below 100ppm. I have noticed that my Black
Moore develops a white spot on his head if I do not do regular water
changes every 7 to 10 days. Can this white spot
be caused by high Nitrate level and what might this spot be.

My ammonia levels before and after water changes is 0. I am using an
ammonia substrate to help remove the ammonia.
