Great - but a warning

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. 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 the tank is never 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 just change one filter at a time.



Hope this helps you avoid the disaster that hit my tankMore detail ...

Filters

I have used the product for many years. I never have any complaints. Only one minor issue. When filling the Bio Bag cut a small hole in the charcoal package to avoid spillage. This product does what it is designed for filtering aquarium fresh water.More detail ...

Excellent value

Excellent value for product. Cheaper than buying in stores.

almost half price (even when factoring in shipping cost!!!)

Aqueon Replacement Filters

They are great and they came right on time.Actually they camebefore they were duebut I was using my last filter when they came.Thank you!More detail ...

Price is great. Make sure to re-use....

Compared to PetsMart this should save you a few dollars. Also don't be so quick to throw these guys away with the Eclipse tanks. We've noticed that the tanks filtration system has a pretty solid vacuum so you'll notice that these cartridges will get dirty after about 4-5 days. Don't worry because it's just the top layer. Pull the cartridge out and scrub the surface with a new toothbrush from your dentist. You know? The cheap ones they give you after you've paid for a teeth cleaning. This should get you a few extra days.More detail ...

price wise

The largest amount I can usually get in a store is 8 I have a lot of fish so this size and cost keeps money in my pocket. I was thrilled to see what I could get from Amazon and will continually order from them.

Eclipse 6 gallon aquarium filters

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 [...].
