Color Name: C - BlueSize Name: 6 -Pack
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.

I bought a load of these and saved a ton of money. Petsmart ships, so no amazon prime savings. Still, what a deal. My big tank takes 8 filters. I was avoiding changing them because of cost.

Funny, I changed all 8 at the same time and threw my tank out of whack. Too much algae and goo left the system with the old filters. I'll change 'em in stages from now on.

I have been looking for aquarium filters for some time for a 6 gallon tank. But everywhere I went--I could not locate them. I was beginning to think that I had bought an aquarium that was out dated. Thank goodness I was able to find them on [...]. I was able to change my dirty filter and it works fabulously! My tank is protected and I now have happy fish! Thanks again [...].

These cartridges are a breeze to use...Open the back top of the filter, pull out the old cartridge and slide the new one in...Gone are the days of removing the entire filter assembly, messing around with wool and charcoal...1,2,3 done...If there is a downside to these at all, it is that they can clog relatively fast (8-10 days)..That said, I think these are a top notch answer to an unpleasant task
