Vacuuming a sand bed or not That is my question

[Kraken]

haha, I think this is a good discussion considering it has always been a big debate about whether they should have a sand bed or not.

Greg, I do not think 6 months is long enough for a sandbed to really "fill up". This is just my oppinion but I had no issues in my sandbed (around 1.5 inchs) for a year and a half. It is only lately that I started having issues.

MJ - The dryrock I used is the same as what has been in the tank when I started. I could take a piece of rock out and some sand, put them both in RO water and test the water to test if there is any level increase. Hmm..might be worth doing =P, and perhaps everyone else who can
participate can do so too and we can pool in our results =D.
