Will a slow sand/rockwool filter out my hydroponic nutrients?

No. A slow sand/rockwool filter will not filter out any of the nutrients in your system. The bacteria in the filter will use a very small amount of nutrients to grow and multiply, but it is negligible. Slow sand/rockwool filters only filter out bacteria, viruses and fungi.
