Thanks
Have to wait until mon/tues to get my tank still
The only thing to bear in mind is that some play sand differs in colour to others, I think the consensus is argos playsand is the lightest of the chain stores offerings....I think
I ended up getting silica sand for £7/25KG (same stuff, but a tiny bit coarser and needed lot's more washing - and I mean lots!)
I will check that its not to orange or anything...
How're you meant to wash sand without getting sand and water everywhere? what're the advantages of silica sand?
