I built this canister system for my classroom tank.
The pump is a Reeflo Blowhole 1100. These pumps have three speeds/amp draws and are as dead silent as any pump I have ever owned. Some of my coworkers came to check out the tank and couldn't believe it was running it was so silent.
The canisters are a mechanical unit (I am using a 25 micron pleated cartridge, I also have a 100 micron cartridge) followed by a biological unit (filled with Bioballs). I mounted the units in a tray I made from an old tool box I had in the barn. The drains are plumbed together for ease of maintenance.
I chose a closed-loop rather than a sump mostly because of the noise factor. As a classroom tank in a class of fourth graders I wanted as quiet as possible. Also, there is less chance of a flood.
On a less positive note, after putting a ton of effort (and I mean A TON OF EFFORT) into resealing the tank (72x18x20 with .5" glass)and installing a custom 3D background, i have a small seep. I am fairly sure water is getting into the trim and seeping through the old (1970) silicone in the butt joints. It is only a few drops per day, but enough that I am going to have to redo the tank or, more likely, replace it with a brand-new 125...
