I have very high nitrate levels (140) for the last 5 year. I have a 90 gallon tank and a 10 gallon sump.
I have 60 pounds of live rock I am running Bio pellets with a Reef Octopus skimmer, added MarinePure High Performance Biofilter Media. I do 20% water changes every week with reverse osmosis water and no my towns water has no nitrates in it. The tank is 5 years old now. I have 2 clowns, 1 Blue Velvet Damsel, 1 Yellow Tank, 1 Copper Line Butterfly and a Chocolate Chip Star with some snails and hermit crabs.
Any suggestions would be helpful.
