gravel cleaning

Hey guys, I've just bought a 100L/ 20 gallon tank and I'm waiting to pick it up at the moment. Very excited! It comes with 2 internal filters (both Aquael 700) and a heater which is great. I was looking into keeping some honey gouramis, platies, neon tetras and maybe some leopard cory's? Nice...

When doing a water change I use the vacuum thingy and go over the gravel.  However, the gravel is tiny and I lose loads of gravel.  Is there a way to stop that?   :good:
