Is there any mechanism to clean my aquarium gravel and debris ?

Question:

Is it advisable to do so ?

Answers:

Another issue which may be affecting the collection of solid wastes is the size of your fish. Larger specimens will produce larger solid wastes. These species include plecos, goldfish, and large cichlids. Unfortunately, there's not really anything you can do in this case except be diligent about your water changes and siphoning.

So long as you don't feed too much and carry out adequate maintenance then there shouldn't be a lot of the detritus left.

there is a fish that you can buy that eats the scum that gets stuck to the gravel and glass that myt be cheaper!
