Size: 6-PackColor: C - Blue
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.

A word of warning. The day after changing my filter three months ago fish started dying. 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. In a rush to catch up, I siphoned out about 30 percent of the water (more than usual), did a "better" than usual job of siphoning up detritus from the gravel. Then - my 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, healthy for more than two years, needed to be started over. Took two months and many water changes before I could safely 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, their blue faces touching. After a few days I remove the older filter and put the newer one - by now doing some biological filtering - in its place. That way the tank is never depending on only a new filter.

Same product you would find at any pet store, but at a discounted price. Picture shown is for a size B or C, but the actual product received is a size A with the notches on both sides at the top. Works great so I have no complaints on its function, especially since Marineland is a well known brand.

There comes a time in any fish's life, when they have to accept the humbling and, perhaps self-demeaning, fact that they are filthy, filthy animals. And each day of their short and filthy lives is full of swimming around in their own waste, breathing it into their bodies and excreting it once more. Sure, there is an elegant grace to their beauty, flitting around the manufactured sea-scape like a Monet painting, but the reality of their truly awful and disgusting environment fortunately does not dawn on their innocent and simple minds.

But perhaps, if only temporarily, Marineland's Rite-Size Cartridge B can make them feel what it must be like to whisper about in a subtropical stream somewhere on an exotic Pacific island. Clean water, home only to the exotic bacteria that must live in those streams, is naught but within a fish's tiny imagination, except for those few times a month when a somewhat disinterested captor decides to change the filter.

And unlike the pristine bacteria-filled waters of the subtropics, the fish need not worry about a piranhas, eels or poisonous frogs to eat it for dinner.

I dont know what it is, my aquarium is always clean looking. These filters sometimes dont last a week before i have to clean them out. They say to change the filter every month.They clog and then the water flows out the overflow pipe.
