Hi Anthony Im just wondering what you mean by Raw water into the skimmer? At what flow rate would sand start blowing around? Is DBS really worth the trouble and expense.
Did people jump the gun with bare botton.
like you said most people run low flow rates through there refugiums bacteria rely heavly on strong currents to bring them nutriunts.
Also particle size and sand depth have little to do with bacteria numbers.
Sorry if this is just all just yesterday's news
