TetraFauna ReptoFilter Filter Cartridges 3 Count, Size Medium, Filter Cartridge Refills

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 💖

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
