Questions & Answers

10 Customer Questions

can you give me the measurements, please? this sound great.
Answer by ChewyOct 10, 2018
This is designed to fit the Marineland Bio-Wheel Penguin Rite-Size C Filter Cartridge within it. It will measure close to 7 x 7 inches. It is specifically made to only fit the Penguin 200 and Penguin 350 model filters.

For the 350, refillable media cartridge, how much charcoal goes into in, by weight?
Answer by ChewyOct 11, 2022
You can use whatever amount you wish to use, as long as the container will stay closed. 1-ounce is the minimum recommended.

If you are using the original filter that came with it and want to add this one what would you put in it?
Answer by ChewyJan 24, 2018
This product can be used with bulk carbon, bio beads or zeolite.

Will this fit the Penguin PRO 275?
Answer by ChewyMay 16, 2022
This cartridge is compatible with the Penguin 200 and 350.

Economical way to keep your Marineland filter fresh

Not quite as easy as buying the filters already made but a whole lot cheaper. They're great for putting extra carbon or zeolite in a tank

Makes me very happy!

I'm always finding ways to reduce my waste and single use items. I absolutely love these! Plus they are super easy to use. I'm going to add a thin floss sponge to help grab small debris but very please.

Good product.

This is great. Works well. Perfect for the Marineland 350 filter as it has room for an extra filter on each side. I used it for some ammonia neutralizing crystals mixed with carbon.

You need this with mess fish

I bought this because my tank has some very mess fish and it wasn't practical to replace the whole cartiage all the time now I just replace the filter part and the carbon part

Awesome !!

I love the fact that I can fill this with my own media. It's a better investment than always buying more and more replacement filters.

Saves money and cheap

Now I don’t have to buy cartridges anymore. Between pond filter about 12 feet long and 2 feet wide more or less and this product, in total spending is about $20.00. I have cartridges for the whole year. Cant go wrong.

Save hundreds $$$

I use these Refillable cartridges in all my Marineland Hobs and they work great. I never buy the replacement filters. Instead I add pinky filter floss to one and Seachem Matrix to the other. I clean them as if they were filter cartridges but these versatile cartridges can be filled with anything from mechanical, biological or chemical filtration.
