jmo but i hate bb tanks it looks so incomplete kinda like the winter without snow a wedding without the ring and so on just my 2 cents though
i had a real good sand the last time i had my tanks up and it was aragonite and a good grade thickness it didnt hardly blow up at all with the current in my tank and it didnt cloud up my water at all like the sand i have now does, and its the same damn sand i bought the last time but its just alot thinnner
i bought it thinking it was the same dang thing biy was i wrong every trime a fish passes gas in the tank there is a cloudy hurricane of sand in the dang tank
im not sure what adding a thicker kind of sand to the tank will do for you but im about to do this to my tank also add my old sand bac in after i rinse it out real good a cup full at a time
surely it cant hurt i mean its all sand right
what difference would it make
just my 2 cents!!!
