Sand?

Ok so the last octo I kept was in a fairly empty tank just some shells ect nothing on the bottom of the tank. What kind of sand should I be using? I know coral gravel is far too course for there senstive skin. I was thinking sugar sand would be a good option. Is this to sharp? Is there a good grit to feel ie rubbing it between my fingers? The other problem is that my tank return is through the bottom in an reverse under gravel filter set up. I want to enshure that it is not going to be too restrictive of the flow. Any thoughts on aquascapeing? I have a tall 130 gallon tank for a not so large octo.

If your return is under a plate, you are going to have some problems with sand...I use beach sand ( comparable to 80 grit silica), but have returns that are above the substrate...you might be stuck with gravel...

A mix between fine sand and goral sand/gravel works well... the CS helps to buffer the pH which can crash otherwise

I spent some time on the phone with the Carib Sea people about this question.

They make a very fine sand Aragamax that's almost like mud. There is one with slightly larger grain size caled Aragamax select. Both are considered "sugar sized" with a grain diameter of 0.2 to 1.2 mm. Neither would have sharp edges and are recommended for sharks and rays. Another slighly larger size grain in offered in the Special Grade Reef sand (1.25 -1.95mm )

The live sand costs more, but even if you don't need live sand, it can be an advantage because you don't have to wash it for an hour. They offer Bahamas Oolite, Fiji Pink, and Special Grade Reef sand - these don't have sharp edges.

Colin has a good suggestion about mixing the grades. I'm going to mix Fiji Pink with the Special Grade Reef Sand.

Um..Quite bad in Hong Kong, they don't have any info on anything, most of the personal aquariums only contain a simple filter, air pump and some sharp hard yucky disguting coral shards, they're not even sand...

If you're looking for Aragamax Live Sand, you'll have to have your LFS order it, if they don't already carry it.

As far as your reverse undergravel filter buy some fine netting at a fabric store and glue it to the top so that the sand does not fall threw the plate

Hey good advice, I think I will go with a 50/50 mix of sugar sand/ coral gravel. My under gravel is made out of egg crate and fine window mesh so I dont have to worry about the sand falling through. I am looking at cold water species (O. Rubecens) so perhaps the wont dig as much.
