Dont want to start any arguments 
But I have a question re sand instead of gravel
The fish I currently have in the tank are as follows
Golden Nugget Plec
Common Plec
Silver Shark
2 small Angel Fish
2 small Clown Loaches
2 Neon Tetras
2 Polka Dot Loaches (currently in a different tank)
2 male Guppies
Just wondering whether sand would be a better substrate instead of gravel for the fish I have above, I know the Polka Dots prefer sand, but wonder if the other fish would be ok with it too
Also its for a new Juwel Rio 180 (180 litre tank) and what sort of quantity would I need, I have a 10kg bag of gravel, that I can use instead of sand, but I wouldnt mind sand
