Review on Zoo Med 78058 Macro External Canister Filter for Optimal Filtration in 75 Gallon Tanks by Prathima Rrain

I have used filters of various sizes from 15G to 75G - Macro and TurtleClean filters are available and sold separately but are physically identical. All are suitable for turtles, although they work quite well in aquariums with fish. First, they have excellent 3-stage filtration with triple filter media: a medium sponge, a coarse sponge over the carbon pads, and a third compartment for biomedia. The device comes with ceramic rings, but I prefer something like the Seachem Matrix for biofiltration. If you are using an aquarium, note that this filter does not have a mechanism for filtering out small particles - this is not a problem for turtles. Secondly, these are quite durable filters. The only issues I had was when I took the device apart to clean it and the clasp or tab broke. Everything fits together well, so be careful when taking it apart. Plastic can break. The motors on it can work 5 to 6 years, which is pretty good for a magnetically driven impeller. Finally, one of the biggest problems with any brand of canister filter is refilling after a water change or shutdown. No problem with these ZooMed filters. This is one of the easiest canister filters I've ever used when it comes to pouring. All in all, I highly recommend this filter.
