Enhance Your Penguin 200/350 Filter: MarineLand Cartridge Media Refill for Optimal Marine Life Care Review

This saves you a lot of trips to the store. Take a large roll of filter material and cut it yourself. Word is just fine and easy to do.

I replaced the Type-C filters I had with this one, added MarineLand Diamond Premium Activated Carbon and emptied the tank in a couple of hours. Crystal clear water ever since! Highly recommended.

I ordered these to use with two Marineland fish filter boxes. I fill them with polyethylene filler and stick them in the media slot. This is my attempt to limit the purchase of traditional blue filters, which are becoming more and more expensive over time. These work great!
