well i know what sand is and i know what gravel is but i have something which sits in between the two ..like gravel that is just about to become sand....its sticks to your hands like sand ..you can model it a bit...

the thing is that i have read a lot of posts saying that the fish like sand over gravel....im just wondering if they would like the stuff that i have??

if i was to describe the size..it reminds me a little bit of crushed nut pieces that would put on top of an ice cream.

Depending on the size and type of your fish, what you are describing should be fine. It sounds like you are describing something like the crushed coral for saltwater tanks. The grain are larger than in sand, but its definitely not gravel.

Many people even use the crushed coral or aragonite in their African cichlid tanks as it helps buffer the ph.

What fish are you planning on keeping on this substrate?

As long as you don't go with any of the sand sifting species, you should be fine. I went with a bit smaller grain (PFS) in my shell dweller tank, but the main mbuna tank has the T grade Colorquartz which is larger than sand and a bit more angular. Hasn't stopped my males from litterally moving mountains on a daily basis.

What peacocks do is not really "sand sifting". They will pick up a mouthfull of sand, suck on it a bit (for lack of a better description) then spit it out. Actual sand sifting species take up the mouthfull of sand, and sift it through their gills while straining out any food. The courser substrates can really irritate or even injure their gills.

Pool filter sand is great. Since the individual grains are usually quite smooth and small, it will work just fine. I have PFS in my peacock, multie and growout tanks. The fish love the stuff.
