Hi, Im a new member and am just about to set up an Interpet RiverReef 50 (94litre) as a mixed tropical tank. I want to use some type of inert sand as substrate but was shocked at the prices of this at my LFS. I seem to recall that its a lot cheaper to buy from other sources if its not referred to as "aquarium sand". Can anyone refresh my memory on what I can buy and where to go for it ? I have been living abroad for several years and knowing the right place to go for things in the UK is taking time to adjust to lol
Thanks.
!! So I ended up buying another sand substrate that's more grainy than the play sand.
