Same filter that filter pump came with new. Good replacement filters.

Perfect thanks! Better price than in stores

Convenient. Easy to change.

Exactly what I was looking for!

These work as advertised

Product was open and box torn and looked like it had been smashed,.. some filters were useable

Good packaging, easy to use

Good quality. Fit well

Expensive

I bought the top fin fish tank that comes with one filter. My tanked looked awesome! I switched out some water once a week and really didn’t even want to do a complete clean at 4 weeks because it was sparkling. I do a full clean and replace the filter with one of these. Within a few days it had started to look a little funky and within a week I had to do a complete change. I hoped that filter was a dud and tried a new one. I’m less than 24 hours in and the tank is already showing signs of muck. I’m really disappointed :(
