No problems before hand, I just tested and saw I had more then enough nitrate naturally for whatever reason. First it comes out of the tap at 10., so even with a 50% water change you go from 20 to 15, not much of a change really. I'd like to induce the plants to use more NO3.

Cause I think was a poor choice of words. They wet/dry are extremely efficient biofilters. In salt systems the accepted norm is typically either take out the bioballs and run without or use live rock rubble in lieu of.

My main concern is limiting K, b/c it does not really occur naturally in tanks.

Thanks
