The filter can be connected to a pump or an external filter by means of a hose. Connecting several Prefix filter in series is also possible.

Review: Had to return the first one - The first canister I received had two baskets both marked "A". Because of this the canister wouldn't close. You need one "A" and one "B" for it to close and work properly. So I exchanged for same thing, hoping that it wouldn't happen again. The new canister arrived with the correct parts and has been working perfectly for over a month. No leaks at all. I have it connected inline with my Oase canister filter and I have it set up with one basket filled with ceramic rings and the other with crushed coral and filter floss. I like that it is very easy to disconnect, clean and reattach. Highly recommend. If you have leaks, check the seals and double check that you have baskets marked A and B for proper fitment.
Review: Good prefilter - It is transparent, which is a big plus for monitoring how dirty it gets. Screw cap is more reliable than plastic clips Chinese alternative has. I like the presence of the 2 compartments and the directed flow. My prefilter has no leaks.

### ⭐⭐⭐⭐⭐ Good prefilter

It is transparent, which is a big plus for monitoring how dirty it gets. Screw cap is more reliable than plastic clips Chinese alternative has. I like the presence of the 2 compartments and the directed flow. My prefilter has no leaks.

### ⭐⭐⭐⭐⭐ Great canister prefilter
*by B***G on August 5, 2022*

Working great as prefilter for my canister. Sicce Whale 120 (140 GPH) runs it well with no noticeable flow drop. The in and out are 16/22mm tubing. I prefer this to the Sunsun HW 602/603 because the downpipe goes straight down and disperses water more evenly.
