MarineLandPenguin Refillable Media Cartridge, Fits 200 And 350 Power Filters (PA10093)

This was a hurry-up purchase. New Discuss and needed to get peat into their water. I've had my 350 filter for years and it works great. Never considered needing the extra refillable cartridges but thankfully remembered they did make these so ordered 2 to go with my regular filter cartridges. Placed them in the slots in front of the regular ones, fit great. So all the regular filtration first then water goes through the peat filled cartridges to soften the water & keep ph more acidic. Using the Fluval peat granules, which can be used in the amount I want, added to the little compartments in these cartridges.

I saw these and thought they'd be made out of that crappy black plastic that you find on cheaply produced dollar store baskets and strainers. I still ordered them, figuring regardless of that they would still work. I was pleasantly surprised to find that they're made of a very sturdy plastic. I dropped one on my kitchen floor thinking it would shatter but it didn't. I only needed one as I only had one spot in a filter that I was going to use it, but it required me to order 2. I figured I'd have a backup. Crazy thing is, I've found that because of how sturdy it is, and the fact that its got the holes in it, I ended up using it to put my coffee mug on!! It stops my mug from discoloring my wood furniture, and any coffee ring just stays on the plastic and its super easy to rinse off! I realized that if I put a piece of thin plastic inside of it, I was also able to use it for cold drinks! The condensation drips onto the plastic, the raised vented part keeps the cold away from the table. I know, I'm nuts right? But is it great for the charcoal? Absolutely! And apparently its the best thermal protective/water protective coaster I've ever had on top of that! I'm actually going to order some more so that I can have more coasters! Perhaps not recommended if you don't want a weird looking grey coaster on your table. : ) Pssst... I also use it for cereal and ice cream bowls!!

The media could not be loaded.  I have a Marineland Penguin Biowheel 200. These fit perfectly and work great with various traditional and ceramic filter media...as you can see from the pictures, I used 2 different types of ceramic media as well as the traditional bio-sponge sheets behind the 2 cartridges. Easy to fill, snap shut and super easy to install. Also very easy to clean. This feels like a much more economical way to go that the traditional disposable filters, which can be a bit pricey. After a week, they are working well and my 33 gal tank is clear. Very happy with this product.

I'm so glad that I found these refill cartridges!If you have a Marineland or old Penguin filter then these are perfect to customize the mechanical and biological filtration components for your tank. They're also great for saving a little money as well. Both of my filters can accommodate four each, two per side, so I use floss and/or blue-foam for the first level and Seachem matrix or activated carbon in the next. So far it works great in keeping my tanks healthy and they're a lot more effective than the prefabricated Marineland Rite Size "C" filters. Those are a total waste to be honest. They clog easily, need to be replaced often, are somewhat overpriced and just create a lot of landfill waste.These cartridges are basically the same dimensions as the size "C" filter except maybe a little deeper. Don't expect to overfill them since the plastic is a bit rigid like the plastic for an under-gravel filter. I could see the little clips breaking if you dropped it or tried to stuff them, but just be careful and you'll be fine.Overall a great product and I would've given it a perfect five stars if it was made of a more flexible/durable plastic.

I was on the verge of throwing away my marineland 350b filter. I hated to do it since although it's not my preferred brand, I do like the small fitler intake compared to the huge flow and of course, I didn't want to throw away all the beneficial bacteria on the biowheels. Not only does this product save you money by not having to buy the ridiculous expensive rite size A cartridges every few weeks, it corrects what is in my opinion the major flaw of this system - lack of flow through the blue filter pads. If you have a planted tank or any tank with a lot of gunk in it, that gunk easily clogs the blue filter pads. My biowheels would stop spinning every day, I would have to take out the blue pads, rinse them back and front, every darn day! It was driving me insane. However, with this product, the flow through the plastic on both sides is much better. I use quilt batting and charcoal. Not only can I add much more charcoal than the pads (my tank has never been so crystal clear), but if I decide I don't want to use charcoal any more for meds or because I'm putting purigen in the other filter on the tank, the quilt batting (you can get a years supply for about what the price of a 6 pack of rite size cartridges cost) is enough. My biowheels are spinning like when the filter was new, I'm saving money and my tank is cleaner than ever. Why oh why didn't I buy this product years ago! This was the best and smartest aquarium purchase I've made! They should sell these in more pet stores and I don't think it's a mistake that they don't because in saving you hundreds, they cost stores that much!

I like it fits My Penguin PRO 275 filter . I was able to modify these with a pair of side cuts very easy.Just snip as close to the edges as possible and snip in the middle, then use Your fingers to rock back and forth till the plastic breaks. This allowed Me to make room for my own Aquarium Filter Pad . Bought some of this Aquatic-Experts-Classic-Bonded filter media available here on amazon that I can cut to fit and make my own filter cartridge . Saves Me money and I just cut to fit . better that the over priced C Cartridges From marineland . in my picture the right one has the modification vs the left is stock. this allows more room to add Your own media . It is quite simple to do and does not hurt anything , it is just as sturdy as the non modded one .

When I found theses I was so happy. As far as I know this is the only brand that makes these instead of having to buy the expensive filters every month. Initial cost is a bit but when compared to filters it’s a no brainer. They fit perfect in any penguin filter. I have the small one and also the largest one. I fill them with carbon and ammonia removing stone and also some bio substrate on the top part. Inside it is broken into sections about every cm so you can space things out and all your carbon etc won’t just sink to the bottom so this offers good coverage. Again I love these things, I’ve had them for years now and no issues. I put filter sponge infront of these as you can see in the pictures. And this also makes it easy to just take the filter out and wash it and leave the carbon etc in longer since it normally lasts longer then the sponge will. Has saved me hundred of dollars.

Súper te ahorras estar comprando a cada rato los repuestos con fibra y carbón activo tu le agregas el material filtrante que gustes súper práctico una excelente compra

I keep extra media in this and it's easy to move to another tank for cycling. I cut strips of sponge to put in the one I'm using to help cycle my new 20 gallon. I plan to put Filter rings in it for my cycled tank once I'm done. I find it fits well and keeps media in place.

Mucho ahorro en filtros

Los clips no se sienten duraderos
