Work Well!
These replacement filter cartridges work well in our fish tank filter. They are easy to drop in and take out without a big mess. We can see when we need to replace them by just popping up the top of the filter. Great price and greater product!

Works great for smaller filters!!!
Fits my small 1.5 gallon tanks filter! Perfect for your needs if you have a small filter like mine. Keeps the tank very clean. After I pull out the old one it is green with algae and fish feces too. Itâs nasty. So it catches all that nasty stuff you donât want to see in your water. I do about 85-90% water changes once a week and change the filter out once a month.

How it is definitely bang for your buck
I loved this filter for my Bettas fish it works perfectly and my Betta fish are happy with it in fact it saves me so much time that I don’t have to clean my Betta fish tank as often it is definitely worth it 6 dollars for 6 filters is awesome because other companies charge way more than that and yet the quality is still the same or better if you want to get your Betta a filter for their tank this is it I loved this product so much and yet the filter isn’t even that dirty one filter can last around 2-4 weeks depending on how much waste your pet fish wastes overall definitely worth the money and taking the filter out is so easy honestly I’m sold for what it is it is band for your buck

Hard to find
I purchased my betta fish, Luna this past July. I ordered the 6.5 gallon tank for him because bettas actually need more room than 1 gallon of water to swim in. Bettas actually prefer 5 gallons or more. I purchased the 6.5 gallon tank from this company and I love it! It even came with a filter. I have been needing to replace the filter for awhile now and I was unable to do so because these small filters are NEVER in stock. It is a tad annoying and I worry about my betta living in water that has a dirty smelly filter. I finally got my hands on the 6 pack for $15 or so. Iâm glad I have a large supply, but it would be nice that I wouldnât have to go hunting around for these filters. These get the job done and fit nicely in the 6.5 gallon tank I purchased from this company as well.

OVER PRICED
These are good. They work well. If you rinse it off every few weeks you can have one last quite a while.I just think theyâre way too expensive.

I get this filter as an extra filter for my tank. It feels like it works great. Makes for a clean tank environment for sure. Water doesn’t look cloudy anymore at all.
