Linear pumps aren't worth the extraordinary up front cost IMO. They are no more efficient than a good diaphragm pump and cost huge money if they ever need rebuilt. Do your research before you make a decision. As an example a Pondmaster AP100 costs about $30 for a kit yet is at least $100 less than any comparable linear pump. You should get at least 2 years before you need to rebuild a diaphragm pump. That means at least 6 years of operation to catch up to cost of linear pump cost. I have no idea how long a linear pump lasts before rebuild is required. I am sure it is over 6 years though.

You noted the difference in your own post. Linears: "If" they ever need rebuilt. You can assume that $30 rebuild cost every couple years as a requirement for a diaphragm pump. I got tired of rebuilding them and just bought one that I don't have to mess with all the time.
 
Great question:

I run a lot of air through the boxes and change the fluff regularly, so they serve primarily as mechanical filtration. Do the gravel (or ceramic rings) I use in them serve as a home for benefical bacterial (i.e. bio filtration)? Sure... but running a box with a sponge will result in a tank with less need to vacuum than one with just sponges.

As an aside, sponges, especially with a bunch of air running through them... or a powerhead on them, will also serve as mechanical filters. I prefer to bubble air through them slowly so that they serve primarily as a biological filtration...and not suck up a bunch of crud from the tank. Switching out the fluff in a box filter takes a few seconds while thoroughly cleaning a sponge filter is a PITA.

So with the boxes and sponges you get mechanical and biological filtration? Or just mechanical? You guys rock I'm about to start searching for 40 and 20 gallon tanks this started out as a pipe dream but may become very real within months

I used the roll 50/50 LEDs. Worked great for my room. I'm not growing plants with them, but I didn't want to.

I personally wouldnt get a corallife type pump just cause there a bit weak for a whole fish tank room but a blower would be perfect. They can run a 2-3 40 gallons but their output is very very limited and there loud! A blower and be placed outside and have a little diy shed over it and with a little expanding foam where the pcv enters the house no noise what so ever from the blower.

Setting up a pvc tube around the tanks and then having some brass T's to control the air flow and your golden.

These are the sponge filters i use and there great.

20 for 45 bucks comes out to around $2.24 each which is well worth it. Never lost fry due to them.

Finished product will look somthing like this

The pvc will hold the air pressure but the brass T's are needed as the closest ones to the pump would need to be restricted the most and the farthest would be the lest restricted.
