Substrate Sloping

[MermaidMel]

What is the reason why the substrates should be much higher at the back of the aquarium and slope down to be much lower at the front?

So that all the waste collects down at the front so it is easier to clean the gravel.

EDIT: spelling

Ohhh
Simple stuff
Does it work though? The waste is so lightweight surely it just stays where it lands lol

If you use plants in your tanks, you will usually put them at the back not the front, so deeper gravel at the back than at the front. In my tanks I don't slope the substrate though.

It is more aesthetic to the eye. It's good for planting as well.

altho if you have pleco's in your tank they tend to rearrange the substrate as they feel fit
