Well I think I figuredout my nitrate source, which looks like the tulfa I used for base rock. I pulled all 78lbs and did a 60% water change and my nitrates have droped to 20. Now all I have for bio filtration in my tank is 95lbs of live sand, 10lbs of actual base rock and 20lbs of live rock, as well as 2gallons of bio balls and 1-2 gallons of coral rubble like what you would find in a calcium reactor. Well I guess I get to learn these lessions the hard way, now I need more and/or live/baserock.
