Tetra ReptoFilter Medium Filter Cartridges for Terrariums, 3 Count, Fits TetraFauna ReptoFilter 20 gal, Viquarium, and Decorative ReptoFilter

These are the cartridges that are used in my waterfall filter that I have in my 20 gallon long turtle aquarium. I think they work very well!! The waterfall filter does require two cartridges though and I just recently got it so when I went to the pet store to get replacement cartridges and saw they were $13 for one box of 3 filters I knew I needed to find another buying option. I was thrilled to find these at under $3 a box! Even though there is a minimum order of 2 boxes I’m still way ahead! I bought 3 boxes for less than I’d have spent on just 1 box! So needless to say, the value is excellent! I also have been very happy with their performance. Turtles are very messy animals, even when they’re babies like mine. Her tank has never been even a little bit cloudy aside from the first 2 days after setting up the tank for the first time, but that had nothing to do with the filter, it was new tank syndrome and once the good bacteria developed it cleared right up and thanks to these filters (and cleaning of course) it’s staying that way. It was suggested to me to replace the filters every 3 weeks, but after a week and a half the cartridges are still working perfectly. At 3 weeks I’ll evaluate again. For turtles replacement will be more frequent, but if you have less messy animals or fish you probably won’t have to do it so often. So overall, I am extremely satisfied with my purchase and definitely recommend 💖

These filters work well to keep my turtle tank water clean and odorless. I have been using them for a couple of years and if changed regularly, water stays clear and fresh.

We've been using the filters for a week in our 20-gallon tank for our 10-month-old Red Slider. Previously, he was housed in a 2-gallon enclosure with filtration, but this little Turtle could put out some waste, requiring constant tank cleansing and water changes. After one week, and a 50% water change out, the water is clear thanks to these filters. I plan to change the filters and stick with the filter manufactirers filter, TetraFauna ReptoFilter Filter cartridges. See the difference between the small tank and the 20-gallon tank, which is using the TetraFauna ReptoFilter Filter cartridges. Update April 8, 2026: I replaced the filters today after 10 days. The filter motor was whining and the filters were absolutely full of waste and debris. I changed out the filters and ensured the filter motor was cleaned out. As I said, this little turtle can put out some waste and these filters can absolutely do their job. The tank water is clear, and the motor is humming along.

Long lasting! I use a lot of of this brand

I've been using Tetra ReptoFilter Cartridges in my turtle tank for quite some time now, and overall, I've had a positive experience with them. These cartridges have proven to be efficient in keeping my tank clean and maintaining a healthy environment for my turtle, JJ, along with seven other smaller fish. One aspect that stands out about Tetra ReptoFilter Cartridges is their reliability. The filtration system effectively removes debris, waste, and impurities from the water, ensuring a clean and clear habitat for aquatic life. This is crucial for the well-being of turtles, as they are known to produce a significant amount of waste. I appreciate the ease of use of these cartridges. They are simple to install and replace, making maintenance hassle-free. Additionally, they fit perfectly in my Tetra ReptoFilter, providing optimal filtration performance. One incident worth mentioning is that I received a cartridge that arrived broken. However, I contacted Amazons customer service, and they promptly replaced it free of charge. This level of customer support was commendable and ensured that I remained satisfied with their product. In terms of durability, Tetra ReptoFilter Cartridges have held up well. They maintain their effectiveness for an 2-3 month period before needing replacement, which is cost-effective in the long run. Overall, despite the hiccup with the broken cartridge, my experience with Tetra ReptoFilter Cartridges has been positive. They efficiently keep my turtle tank clean, and the excellent customer service provided reassurance of the brand's reliability. I would recommend these cartridges to any turtle or fish owner looking for a dependable filtration solution.

keeping our tank clean and turtle happy

Great item. Thanks

These filters are a direct replacement for the filters that our rock waterfall use and they hold up really well considering they are filtering the water for 2 frogs and a very large goldfish. When the water slows down coming out of the waterfall, we just pull these out and rinse them clean and reinstall them. We usually don't have to completely replace them for about 3-6 months. When you first install these you need to rinse them off with cold water to rinse the carbon dust off of them and activate the carbon. I will continue to buy these until we no longer have a use for them. Pros: price, ease of use, last a decent amount of time Cons: comes in a 3 pack (we use 2 at a time)

Tetra's Medium Filter Cartridges are fantastic! Easy to install, efficient filtration, and long-lasting. Keeps water clean and odor-free. Highly recommended for reptile tanks.

Ampliamente recomendable, en su momento lo volveré a comprar.

Son buenos aunque no duran tanto como hubiera pensado, solo tengo una tortuga y tengo que cambiarle el filtro cada semana o a lo mucho cada 15 dias, lo cual para mi es lo mismo que antes ya que lavaba la pecera justo cada 15 o menos

ok

I ordered the filter as well from Amazon. Works well to clean the water in my turtle tank. Easy to install/ replace. A bit pricey than my local store though.
