This may be a silly question but when doing water changes, do you guys normally vacuum your sand-bed? This is something that I have never done and was wondering is this is considered a part of "best practices" when maintaining your tank. For those that saw, I do have a pest algae issue in my big tank but it's only on 1 rock and nothing else. I just started to run a fuge so lets see how that goes, it's been only about a month now and I was running gfo but have since stopped as it is pricey. Off hand I do not know what my parameters are but will test when I get home. I only have 2 fish in that tank (72gal) and I know i do not over feed. Which is leading me towards the sandbed
