Marineland PA0140 Magnum Micron Cartridge, 1-Pack

I have a Marineland 250 Mag Filter that I move from tank to tank for polishing at cleaning time. Having extra Micron inserts is very important to speed my cleaning after meals..... This works great....

This is part (the filter part) of the larger HOT (hang over tank) cannister filter by Marineland. This unit pulls the fine particles out of the water MUCH better than standard power filters. This sleeve needs to be rinsed off fairly frequently. Not for everyday use, the blue sleeve that comes with the power filter is for that. You have to have the Marine HOT power filter in order to use this filter. This setup is for polishing the water when your tank needs a little pick-me-up water clarity. Makes the tank crystal clear!(I am talking about the whole unit, power cannister that this filter fits into).

The fish look like they are suspended in air the water is so clean. Couple of drawbacks though, the unit is somewhat noisy and bulky. Will not fit just anywhere. Be SURE to FILL IT UP COMPLETELY before you turn it on. Also, this blows the water out of the tube pretty quickly and this cannister is NOT for small aquariums. If you use it on anything smaller than a 30-40 gallon, be prepared for the water to slam your little fish all over your tank. WONDERFUL for larger tanks!

I've used several of these on my 180 gallon aquarium over the past decade. Great filter. Never had any problems with them.

This is a great product. However, it does require frequent cleaning with bleach and water solution. The instructions for this come with the product. It really gets all the fine particles out of your water. It leaves my tank sparkling clear.

There are only two filters that can polish water the Diatom by Vortex and The Magnum 350 by Marineland.

With both filters it's important to note that neither provide bacterial filtration and should not be used on a regular or permanent basis.

These filters work best when used as a part of your aquarium maintenance regime. Or when you simply want your tanks water to look perfectly clear.

I've used a Diatom Filter for 35 years they haven't changed since 1972. They're a bit cumbersome to set up and break down but the results are incredible. The Diatom can filter out particles, pathogens and parasites down to one micron in size. It's the only filter on the planet that can actually filter out ich.

The Magnum which can convert from a standard mechanical canister filter to a water polisher by using these Micro Marineland polishing canisters. However they're limited to filtering out down to 15 microns 10 micron can be seen with the naked eye. You'll get "some" polishing effect but not crystal clear clarity.

The Diatom Filters use diatomaceous earth or DE as a media Marinlands Magnum uses an ultra fine 200 micron mesh.

A Diatom is a fossilized micro organism from millions of years ago. These tiny fossils are pulverized into an extremely fine powder.

When the powder attaches itself to the filter bag of the Diatim it coats it with such a fine strain that any particulate matter down to one micron in size is removed. This is why water that has been filtered with DE looks so amazingly crystal clear and pristine.

In fact, if you turn off your aeration it looks exactly like your fish are suspended in mid air. The water is that crystal clear.

DE can remove algae blooms, murky water and hazy water from new tank syndrome all in a few hours.

These cartridges can't really compete as far as the end results but for those who are looking for something easier the Magnum may be just the ticket but again, the results won't be near as dramatic.

You can recharge the cartridges using a 2 to 1 bleach solution just make sure you rinse it well after and then soak it water treated with a product like Prime.

These are an easy to use alternative to the more complicated and cumbersom to use Diatom by Vortex Filters. However, the Diatom filter build quality trumps the flimsy Magnum 350.

Each cartridge arrives in their own box, well packaged and delivered quickly.
