The Marineland Rite-Size Cartridge C is a must-have for anyone with an aquarium that uses a filter system compatible with this cartridge size. I’ve had a hard time finding these in stores, and when I do, they are often priced way higher than I’d like to pay. That's why I love getting them on Amazon – they’re so much more affordable and I don’t have to deal with store shortages.These cartridges are easy to install, and they do a great job of keeping my tank clean and clear. They’re designed to remove impurities, odors, and debris from the water, which keeps my fish healthy and my tank looking great. The quality is consistent, and I can rely on them to do their job without fail.For the price and the convenience of getting them delivered, I highly recommend these cartridges for anyone with a Marineland filter. It’s a great deal compared to buying them in person at the store, and you’ll save both time and money!

I just crucified a competitors filter cartridges in review, so call me a bit discerning. The marineland filter cartridges are a breath of fresh air after my initial experiences using a competitors product. After my unfortunate experience with a 50 gallon version over the back by someone else I was left jaded and went canister filter all the way. My wife had some growing goldfish that I upgraded to a 20 gallon tank which motivated my purchase of a marineland 75 gallon penguin filter. I crammed that thing into a 20 gallon tank still wondering if it would do the job and lo and behold it perfomed admirably, the water cleared up quickly and filter cartridges lasted 3-6 weeks (occasionally we have algae blooms in our goldfish tank that isn't the filters fault) as opposed to the 3-6 days we were used to previously.Fast forward about 8 months and my wife's goldfish have migrated to my 54 gallon corner tank and I moved the marineland over the back filter with them. It has performed excellently in the bigger tank without any significant changes in cartridge longevity. Water stays nice and clear, minus the odd algae bloom. I will have to switch to a canister due to space constraints (I can't put the lid on my corner tank with a large over the back style) but I'm 100% sold on the effectiveness of marineland filter cartridges.Marineland has proven to be the most effective over the back filter I have used with this style cartridge, add in the affordability of the unit and cartridges and it's an excellent system for anyone with over the back filter needs.

The Penguin Bio-wheel pumps are great: quiet, effective and long-lasting. (I have a 170 filter in a 39 gallon tank.) These size C filters are widely available, but the Amazon price is much lower than at my not-so-nearby pet store.But a word of warning. The day after changing my filter three months ago I began losing fish. Next morning my 6" long Plecostomus was dead. Then three Clown Loaches, each about 5 " long. Within a week I had lost 18 of my 20 fish. Yet there was no sign of disease.A water test and much internet searching finally pointed out what I had done wrong. I had neglected my tank for a few weeks, so in a rush to catch up, I siphoned out about 30 percent of the water (more than usual), doing a "better" job of siphoning up detritus from the gravel than I usually do. Then - and this was the biggest mistake - I replaced the Penguin filter too! The result is the water chemistry changed too quickly. The Nitrates spiked to a deadly level. My tank, that had been healthy for more than two years, needed to be started over after many water changes and waiting more than two months to add new fish.I visited perhaps a dozen "fish forums" and only one had a comment saying "don't change filters when you do a water change.' The Penguin filters and the box they come in carry no warnings. What I (and you) should do is simple: space your water changes and filter changes a week or two apart.Now knowing how important the "aged" filter is (especially in a tank like mine with no under gravel filter) I've started this habit: there's just enough space to get a second filter flat against the old filter. After a couple of weeks, I remove the older filter and put the newer one - by now doing some biological filtering - in its place. That way there is never a time when the tank is depending on only a new filter. For larger tanks (say 55 gal and up), the 330 or 350 Penguin pump holds two filters side by side, so the advice here is to change only one filter at a time.Hope this helps you avoid the disaster that hit my tank.

these are OK at best , but the better option is to buy your own media and cut to fit I bought Marineland Penguin Refillable Media Cartridge right here of amazon and some Aquatic Experts Aquarium Filter Floss duel density ( see my review on the Marineland Penguin Refillable Media Cartridge on how to easy mod the unit) This blows away these OE filters in every way saving money to boot. I just cut to fit and I am good to go

No me gusto el producto porque el carbón se cae o se sale de la parrilla, viene muy delgado, en la primera fotografÃa el filtro de la izquierda es el último que me queda, nada que comparar, se nota lo limpio a comparación del que acabo del que han enviado...en la siguiente fotografÃa se nota como la caja viene manchada y hasta el fondo de la misma tiene muchas partÃculas de carbón esparcidas...de verdad esperaba un producto similar al que habÃa adquirido, ni modo, no lo regreso porque me urge para mi pecera...gracias.
