what replacement filter pads do I get

Answer by ChewyOct 07, 2019
The Medium Zilla Reptile Terrarium Filter Replacement Cartridges should be used with the 20 gallon filter and the Large Filter Replacement Cartridges should be used with the 40 gallon filter.

Is the Zilla Aquatic Reptile Internal Aquarium Filter supposed to create foamy bubbles? The reptile is a tiny turtle.

Answer by ChewyJun 19, 2020
This product creates bubbles on the surface of the water. This filter is designed for terrariums that hold turtles and other aquatic animals. Check out the video below.

How clouds the water splash. The one I have is sooo loud??

Answer by ChewyDec 07, 2021
The sound of the water falling is relative to the distance it has to fall. The farther the water is from the lip of the filter, the louder the water splash will be. If you can keep the water level up so it is close to the outlet of the filter, it will be much quieter.

Will this work for a low level water fall,about 2 inch of water,in tank?

Answer by ChewyDec 31, 2019
The water level needs to be at least halfway up the filter but below the lip. If using the 20 gallon filter (5 x 4 x 8 inches), you'd need a water level of at least 4 inches and for the 40 gallon filter (6.5 x 6 x 11.25 inches), you'd need a water level of at least 6 inches.

Not easy to clean.

The problem with this item is that it gets clogged easily and doesn't clean easy. Had to get a second one due to this issue because the first one stopped pumping

Zilla internal filter 40 gallon

This filter does help to keep the water clean. The only complaint I have is the noise level. I have to turn it off at night so I can sleep. I have 2 smaller, quieter

This filter does help to keep the water clean. The only complaint I have is the noise level. I have to turn it off at night so I can sleep. I have 2 smaller, quieter filters to carry the load at night. I think my RES appreciates the quiet nights also.

Just okay

It's working okay for now, but we haven't had it in the tank for week yet. The top DOES NOT FIT and will not stay on.

Great Filtration!

The Zilla Aquatic Reptile Internal Aquarium Filter is fantastic! It works efficiently, keeping my tank water crystal clear. I have used different filtration systems

The Zilla Aquatic Reptile Internal Aquarium Filter is fantastic! It works efficiently, keeping my tank water crystal clear. I have used different filtration systems in the past, this brand is the BEST for my turtle tanks! The adjustable flow control is a great feature, letting me customize it to fit my tank's needs. It’s easy to install and clean. We use a metal/rubber clamp to keep all our filters attached to our turtle tanks. We use a sponge and the hose to rinse off any guck that formed. Super easy to clean! A solid choice for anyone looking for a reliable filter. Highly recommend!

Awesome

Works perfectly for my turtle tank. I had a more expensive filter that burned out. This is in the water and don’t have to worry to much about it burning out. Also

Filter built for turtle tanks

Absolutely love how quickly this new filter has cleaned my turtle tank, plus my turtles love climbing ontop the lid to bask.
