Review on Marineland Polishing Internal Canister ML90770 by Robert Smithlin

So I've had two of these units for about six months now and they work wonders for my 13 inch 120 gallon river cutter. Unfortunately, due to the way my tank is set up, I can't move a giant tank onto a regular can without, well, emptying it and letting it roam around for a bit. I have 3 Magnum Micron cartridges. I use one of the canisters for water purification and the other I use for the carbon filter. Cleaning is very easy compared to other filters I've had before. The ability to bleach the micron filter overnight or for days with a gentle post-soak cleaning is a great break from the need to deep clean everything. If any of these get dirty (and they get dirty and clogged for 4-5 days ), It's insanely easy, just swap out one of the cartridges for another. It takes me about ten minutes to clean my old one, now it only takes a few seconds and it's ready to go again. Wise clarity, I have committed the foolishness of using rocks at the bottom of my tank, which is where, as you may know, their excrement accumulates. Hide. The old filters I had right now couldn't do much about it, so I had to clean them by hand. These filters pulled everything out from under the rocks and cleaned the entire aquarium. It's crystal clear. I've had them for about 20 years and I'm sure this is the happiest time I've ever seen. BTW, I bought them when they were $70 each and it was worth it. Do yourself and your essence a favor, take this.
