Marineland Magniflow Canister Filter For aquariums, Easy Maintenance,Black

This is a nice sized low cost under the tank filter.After running just a day or two the tank looks significantly cleaner than with the previous top mount filter.It is super quiet and has a great flow for the tank which not only helps keep the tank cleaner but is healthier for the fish to have a slight current.My only two complaints:The tank mounting tubes are really flimsy plastic and the discharge in particular has a single outside tank suction cup to hold it on. This was a problem for my tank as I had a back screen I had to cut thru to allow it to reach the glass.Second complaint is that it uses these small replaceable carbon bags. If it wasn't for these the entire filter element would last 3+ months and would be washable/ renewable, especially with a plant-fish in the tank. I know carbon filters make it look good right away because there is no biosystem that needs to build up. I am trying to figure out a way to design them out with a different filter element.With regard to the element packing inside the filter each media has its own shelf, it's very clever and easy to work with, gives a lot of options for media (which don't seem utilized)Edit: In response to the manufacture reply to my comments and a little more time with the filter I will make a correction here.First: Many people have visited my home and noticed how quiet this filter is and how clear the tank is. It is that big of a difference compared to a top mount.I appreciate the response of the manufacture to offer an additional suction cup to the discharge to give me more confidence I won't come home from a trip to an empty tank :-)My first reaction to the carbon bags was not great, but this filter does offer a great deal of flexibility for what to put in the media trays so pretty much any filter bag you buy at a pet store , or in my case if I want to go with non-activated charcoal is possible.With those corrections I am totally happy with this tank and give it a 5 star, now including customer service.

I inherited a tank from a friend's Widow who couldn't keep up with the aquarium after my friend's passing. The aquarium was horrible and it took me 3 months of constant water changes, cleaning, and gravel washings to get the aquarium environment healthy enough and stable enough for fish to not only survive in it, but thrive. No matter what I did the aquarium was always cloudy with the old filter. When I changed to the Magniflow 360 the water cleared up within 24 hours and has remained that way ever since with the exception of a short period of time where I included Sera Superpete in the filter media to help bring the PH levels down and get the GH under control. Even then, despite the slight yellow-brown tea color staining, the water was crystal clear. In fact so clear, that if it weren't for the aeration system you wouldn't be able to tell there was water in the aquarium. Even looking through the side of the aquarium, end to end, the water is still so clear that the current from the outflow and the aeration system are the only things that give away there is water in the aquarium.You still have to do regular cleanings of the gravel, glass and filter, but instead of having to do it every 3-4 days, I do water changes every two weeks and clean the filter once a month. The water is amazingly clear and the fish are thriving.I keep 1 Comet Gold Fish, 1 Plecostomus, 5 Black Skirt Tetras, 12 Cardinal Tetras, and 4 Wag Swordtails.I wouldn't think of it as fix all, but it is fantastic at doing what filters are supposed to do. I would definitely recommend it to anyone looking for a good filter. While it is more of a process than a biowheel filter, its still relatively easy to maintain and if you love fish as much as I do, its very much worth the extra effort. I love the versatility of media that can be used in the filter as well. Very easily adaptable depending on the needs of your aquarium. If you don't have one of these, you really need to get one.

Why in the heck does a ~$200 filter just stop working after less than 24 hours?! I'm not just talking some bubbles in the system or even a leak- like motor COMPLETELY DEAD. I did NOT run it dry / without water at any point (duh), nothing abnormal happened to my knowledge that would cause this. The system was airtight and working ok for ~20 hours until I came home to find the tank water completely still and this big heavy(!!!) filter useless. I seriously cant believe that SUCH an expensive product would just quit like that. I suppose I'm grateful I didn't come home to a flooded room, that wouldve been worse. However, I'm still irritated. I ended up going with the C-530 (unfortunately from this same company) for my 75 gallon.I have a smaller Marineland canister for my other tank that has lasted for 4+ years, so I guess my experience with this particular unit was a fluke?? The larger 530 mentioned has worked great for about three days now (fingers crossed!!!).PS- despite the issues, I still prefer this brand's filters over Fluval (theirs are noticeably flimsy?!)... which surprised me! Even with with this recent Marineland dud, I can't say nothing bad about the general sturdyness of their quality (filter baskets, tubing, etc.)Def recommended buying through Amazon though, so a return is possible/easier if you get a defective unit like I did.
