dvanacker; no, even without the carbon addition I had unmeasurable Nitrates. I just add it to make sure there are less Phosphates...
About the LR; It's just fine-tuned BB-methodology; export before it breaks down. But when you exporting too fast corals will turn pale and starve.
It's a matter of tuning the technique, measuring parameters and carefully watch how corals react to that.
I think I could run this tank with even less LiveRock.
The RDSB wasn't installed to lower Nitrates, but to hold detritus and dirty up the tank a bit. Don't know what it actually releases, but my corals look better now.
It's a safe idea I can always take it out if something goes wrong
Kinetic; it's a plexiglass box
I just raised the Magnesium level to get better growth and to increase colouration (especially blues) I experimented with different levels.
I never had any algae issue so I didn't raise it for that. I maintain a level of 1400-1500.
