If you want to get some idea of how your decor will look in your tank before you buy it, check out this 'aquascaping aquarium' which has been set up at Maidenhead Aquatics @ Woking.
It lets you experiment with different wood, rocks and plants in-store to help you get the effect you're after.
We reckon it's a great idea. With the large range of decor at the shop to choose from and play with, you can find out what works — and what doesn't — before you part with your cash.
Take a pencil and paper and sketch out the effect you're best pleased with — or better still snap a picture — so you can re-create it again when you get everything home.
