Well, I've got my phosphates down to .03 on the other tank, with the help of Foz Down. The stuff works pretty well.
But my nitrates are still at 20 -30 ppm. When I combine the tanks to one sump, I am assuming the nitrates should be cut in half or more, and then with the bio pellets running on that sump, should take care of the rest.
Do you think the SPS will mind temporarily high nitrates? They have been used to zero nitrates and phosphates for some time now.
