Moving Bed Filter

[TigerOscar11]

OK, so i have seen many videos on moving bed filters
What i want to know is, will these help in making the water clearer?
May seem like a silly question but i wont know the answer if i dont
I was thinking of doing a DIY moving bed filter but want to know if it is worth it?

I've never used one but from what I've seen they seem to have very little in the way of mechanical filtration. I think they're designed more for increased biological filtration. Do you know if your water clarity issue could be some sort of algae or bacterial bloom? Or is it particulates? You could try adding filter floss as a water "polisher" it will catch small particles of debris that make it through sponges. Just make sure it is the final stage of your filtration.

It's not that my water is cloudy or anything, it's fairly clear, I'm just looking for cheap and easy way to get that crystal clear look

Fluidised beds are great for high surface area contact with things. Chemical reactors use them and sand bed filters use them for high biological surface area filters in a small space.
 
The only way I can see of them giving you crystal clear water is by allowing you to turn over more of your main filter to mechanical or by allowing you to use some of the chemical water polishers somewhere. Some people swear by purigen for water clarity, some by filter floss, but it does depend a whole lot on why you have cloudy water in the first place.
