No signs of my brick degrading as others have experienced - though mine is a Marine Pure product, not Brightwell.

I've been adjusting and experimenting with carbon dosing for over a year now. It took me a while to dial everything in because I upgraded my system in between and I've also juggled many of the popular nutrient export methods to find a combination that worked for me and my system. To not go into too much detail, the issues I experienced with carbon dosing all revolve around using too much and keeping my nutrients too low relative to the rest of my parameters. I've lowered my alkalinity and calcium from 10.0 dkh and 450 to 7.8 dkh and 410, phosphate has always naturally settled at 0.03 ppm and lastly I use to keep my nitrates at 0.5 ppm but get much better growth and color in my SPS when I keep it around 5 ppm. These adjustments have also allowed me to become less reliant on my carbon dosing (2 ml of NOPOX a day on a 250 liter system).
