I have been doing 15 gallon water changes everyday to try and drop my nitrates. I can't figure out why they are high. All of my other parameters are fine.
Nitrate-20-40
Nitrite-0
Ammonia-0
pH-8
temp-80
salintiy-1.025
Any suggestions on this? I added an organic substance called Special Blend. I was told that this would help dramatically, but I haven't seen a change. I have a Berlin protein skimmer and an old school wet/dry.
