Umlecoa 8/16/32 Pack Rite-Size C Filter Cartridges Compatible with MarineLand Penguin PRO Power Filt...

Our Experience

I finally decided to try these Umlecoa filter cartridges after my old ones wore out and I was tired of overpaying at the pet store. They fit perfectly in my MarineLand Penguin PRO Power Filt, no fuss there. The price point was a definite plus - cheaper than the originals but just as effective.

I've been using them for a week now and my betta fish seems happier already; the water's clearer, too. I like that they're easy to rinse and reuse. My only minor critique is that they can be a bit tricky to snap back into place after cleaning, but once you get the hang of it, it's no big deal.

All in all, I'm impressed with these filters. They've made maintaining my aquarium easier on both my wallet and my time.
