dirty tank

Hi Guys,

I've noticed that my tank is getting quite a lot of dirt on the plants and decorative items, is this normal or am I missing something. It's happened on all 3 of my tanks since I started fiahkeeping and they gradually get dirtier and dirtier.

Any ideas welcomed, I do a 25% water change weekly and clean the tank at the same time. I have mostly real plants with a very large piece of monapoli root wood (sorry about the spelling) with a few other decroative items, caves etc.
