DSB in refugium

[Ed Kazz]

Should a deep sand bed in the refugium be vacuumed ?
Its time for a water change and heard it was necessary to break up the surface of the sand (but NOT disturb the lower layers).
Sand bed is about 8" deep with some cheato.

Thanks

Well i don't know about vacuuming but just stir the top layer to prevent detrius buildup
