Wondering what you all are doing for nitrate levels. In my aggressive FO, 75 gal bowfront, 1 dogface puffer, one hawaiin big eye squirell, cc for substrate, I carry trates in the 60 to 80 ppm range. I would really like to go DSB in my aggressive but cannot have a cleanup crew as they will become lunch. I am running a fluval 404 canister and realize that this is a major source for my trates. Going to add LR as I am using base rock currently and am about 20lbs shy of where I want to be. Will this help in reducing the trates if I use the canister for mechanical only and remove the "bio-everything" I am curious about better options for keeping trates low in an FO aggressive, without having to change 15% of my water every week. Currently change water once a month and all other levels are great, constant ph, 0 trites, 0 ammo. Am I stuck between a stony coral and a hard place? Also wondering what levels of trates all other aggresive tank owners carry.
