Undergravel Filter Box (UGF) -The best Filter for Caridina shrimps?

In this video I will explain the advantages of an Undergravel Filter Box and how to use it in my opinion.
I will also explain the structure and function of this type of filter.

Of course, I will also explain how I normally set up my filter boxes for my Caridina breeding aquariums.
In my opinion, these filters are ideal for keeping Caridina shrimps such as Chrystal red.

If you are interested in a UGF box, you can order one using the following affiliate link. The video is not sponsored and I have paid for all the boxes I use myself.
However, if you order a box via the link you can support my channel - the price is the same for you.
