💧 Marineland PA0140 Micron Cartridge: Optimal Filtration for Magnum Canister Filters - 1-Pack Review

I like these filters out of the box and first and maybe second use. After that, they seem to decompose. I ran one through the laundry on the gentle cycle just to see if that would help, and of course it was worse. They are quite expensive for spot cleaning. I generally only use mine when needed in my reef tank to polish the water. Now I take the activated carbon cartridge and stick it in the bottom of the filter and then wrap it with filter thread. It's much more cost-effective and one-off if…

Excellent filter. Really cleans and polishes the water. I have three FLUVAL FX6 in a 200g tank and they do their job well but! The water wasn't crystal clear. This filter in the Marineland Magnum really cleans the water, I really like that. With this filter everything is now crystal clear. Follow the cleaning instructions carefully. Bleach and water required, soak for 24 hours, remove and rinse well. That works great. However, do not leave the filter in the water and do not bleach it again…

Not suitable for DE and damaged part cleaning. The original cartridge that comes with the polishing canister is of higher quality. I used these for DE/polishing and the cartridge did not "load" DE into the canister. After 90 minutes, the feed water (5 gallon pail containing 6 teaspoons of DE) was still very cloudy, indicating the DE was flowing through the cartridge/filter. The original cartridge that came with the polishing filter was fully charged in about 20-25 minutes. Also, following the…

I bought two separate Marineland polishers and they worked 100% perfect with the filter pad that came with them. However, I bought this replacement filter a day and two after my polisher completely stopped working. It started making a ticking noise and the water didn't move. The polisher burned through completely. I replaced it thinking it was a canister and not a filter pad but just this week I replaced the filter in my second polisher with this filter I just bought and it did exactly the same

I see some reviews had trouble refilling this D-Earth device. I've used it this way about a dozen times and haven't had any problems. I also used a 5 gallon container and filled the bucket with water high enough to cover the unit as instructed. The machine was then turned on and 6 tablespoons of D-Earth (Harris Earth Food Grade) was added. It took about 20-30 minutes for the water in the buckets to clear. I'll let it run for another 20 minutes. I have found that when moving the unit from the…

Although marketed as an outdoor product, I bought this to keep our terrier away from cat food. He can jump and move objects to get the kitten's food. A) The roof, in the trash can. If you use it indoors, it has a gravel deck. Some splinter. Also, part of it broke in transit, but since I planned never to use it, that wasn't a problem for me. The fairing is torn so I could either ask for a new segment or glue and clamp it. B) The paint is quite thin so I'm wondering if you're buying this for…

This filter cartridge does a great job of removing airborne particles from my aquarium. I change twice a week and use two filters alternately. My first pair lasted a year. My best advice is to follow the cleaning instructions and avoid using mechanical cleaners. Don't use your fingers, brush or anything else. Simply spray with water to remove as much dirt as possible, then soak in a 25% chlorine bleach solution for about 24 hours. Then rinse thoroughly and air dry. After this treatment they…

There are only two filters that can purify water: Vortex's Diatom and Marineland's Magnum 350. It is important to note that both filters do not provide bacterial filtration and should not be used. regularly or continuously. These filters work best when used as part of the maintenance of your aquarium. Or if you just want your aquarium water to look crystal clear. I've been using DE filters for 35 years - they haven't been changed since 1972. They're a little fiddly to install and disassemble…
