Works pretty well! Just put them in a bag and throw them in the back!

The only caution I would have to this method is that if you don't remove the source of nitrates they will come back. Be it source water, sand bed, filter floss, over feeding, etc.

In RomaFan's case, water is already being changed and it's not helping, so the source is very active and removing the source needs to happen first, then a massive water change afterwards!
