Replacement Filter Carridges Medium-6 Pack 09830

Item arrived timely and in excellent condition.

I like this product, always get the same brand zilla and size medium for the turtle's home.

My only complaint is that they don't seem to last as long as I thought they would. I do rinse them out one or two times but really they probably last 1 - 2 weeks max.Maybe that is okay though because it means they are filtering the water well.

Use these in my tank with 4 turtles and they definitely do their job. I do have to change them rather frequently, every 2 weeks or so but there are 4 turtles and they are messy. I've purchased these at the pet store for much more, this is definitely the best value.

I got these when my turtle had a medium filter in a 20L tank and they worked well but I recommend adding a sponge in the filter behind it.

The Zilla Water Filter itself is really good. They claim the cartridges last a month, but that's not been my experience. I replace them weekly, and I keep the tank clean. But overall it's a good buy.

Love these filters! So far these are the only ones that will keep a Red Eared Slider turtle water clean and clear! And the best thing is, we only have to change the filter every 2 weeks.. that’s how good they are!

I love these and the filter itself. I've bought this a couple times. My turtle doesn't mind the gentle current and it does a good job of cleaning up after him.
