If adding tap water with relatively high nitrate levels when doing water changes, how quickly will they be taken up by plants?
What are the effects on fish during such nitrate spikes?
How do these spikes compare with those resulting from adding ferts?
Should you consider some way of reducing nitrates in the tap water, and if so how?
