FANTASTIC for aquarium maintenance!
I use the Marineland Magnum Polishing Internal Canister Filter for aquarium maintenance. We put them in the tank(s) and then begin maintenance which stirs up all of the debris and substrate. The microfilter traps the particles out of suspension while just recirculating the water and clearing it all up. This saves time and money as we don't have to do so many water changes, just this "polishing" function. Completely submersible and we can direct the flow sort like an underwater leaf-blower. Then we pull it out, insert another micro filter cartridge and go to the next tank. I recommend purchasing several filter inserts so you will have time to clean and dry them between uses without waiting. We use the bleach treatment after each use. I've been custom designing tanks and keeping tropical fish since the 70's I HIGHLY recommend this filter!
Unbelievable results
Having the 38 gallon bow front kit, the marineland bio wheel 200 HOB is sub par for this set up, added this canister finally took the haze out if the water, I now pretty much use the bio wheel as a holder gir mh ceramic rings with just a pre cut piece of media in front, and use the canister as my main filter. Controlling the flow problematic but with some proper position have jt jusg right. So wish they would make a flow control. But other than that it us a awesome filter/polisher tank is now crysral clear water parameters are all perfect now we can populate the tank.
Extremely fast filtration
I just started a 60 gal plant tank. The substrate is all black flourite products with rocks and malaysian driftwood. 30 ltr total bags and what a mess, the water was almost black. i purchased a fluval u4 and ran for 2 days and still there was no change in the water. installed this filter system and by morning it was 75 % clear. by the end of the day it was crystal clear. This is the perfect start up filtration system for any tank. Highly recommended. The only draw back is the filter output is too high for my needs and i need to find a way to disperse the output as i need almost still water but require this level of filtration.
Thank you for your wonderful review! To help reduce the flow, you might remove the diffuser, and put a piece of filter sponge on the end of the output.
