    Surface area, as big as possible, I have a 3 foot as a sump and a least half is my DSB.

    Oh, please don't go by this article too much... it's so out-dated and full of bad info.

    Flow over a DSB should be as much as you can get without creating a sand storm. As others have said, surface area should be as much as you can reasonable get.

    Aside from the fact that the author doesn't know how to write in complete sentences, I think the info is more or less accurate. Sand grain size is really, really important. I do think that a mix of fine sands is probably the best for our purposes. As far as diversity goes, yes, more is better. However, we don't quite need as much diversity as is found in the ocean. We just need enough diversity to keep the sand bed populated enough to keep the sand grains from clumping together.

    Agreed sihaya...he / she doesnt cpmplete a sentence making it difficult to read (maybe thats why i gave up after about 3 mins of reading !)

    Quick scan of the doc did however seem interesting....will go back & read again.

    Thanks for your input again:thumbup:
