And you can get pretty much the same thing as this for around the same price + warranty + professional look if you buy a normal canister
Not at all. I have NEVER seen a canister filter for under $200 that has over 900 GPH and over 20L of bio media capacity and operating with a quality pump.
The ehiem 2080 pro 3 has 14L of possible bio media capacity and only about 340 GPH flow rate for $400-$500 US.
This is a good idea, but if you want to sell them (which you never specified whether this was just personal or if you wanted to sell them or whatnot) you are going to have to cut price down quite a bit. Right now for less then $200 you can make a w/d that could filter a tank 3x as big, have more room for mechanical filtration, more room for bio filtration, nitrate removing abilities ect. And then there are those that like canisters that will either go FX5 or Eheim.
If I was going to sell them I wouldn't put the plans and materials on the web for everyone to see. Including the price for all the materials
.
The Fx5 and Ehiem won't even come CLOSE not by a HAIR to the flow rate and capacity of this filter.
I have a Moddified Fx5 that holds 11L of bio media and over 320 cubic inches of mechanical filtration.
To make this really worth it cut costs, get a better pump (mag drive or just something a little higher quality that can be put under some load, as this is a no-bypass filter) and there ya go.
Quiet One pumps are not good? They are mag drive. Why cut cost ? What is to expensive with this setup?
Oh and about the better mechanical filtration, you have so much room in w/d filters that you can run 3 pairs of micron filtration bags (200, 100, 50) along with other mechanical filtration and get crystal clear water and STILL have a huge bio area.
Thats fine, I can run 100, 50 and even a 10 micron pad if I wanted in the canister filter. 20L of bio media is plenty for a 180 Gallon tank.
Wet Dry filters take up a lot of room where as canister filters take up very little.
Don't at all think im trying to put down Wet/dry filters because they are great and if you have a very large tank, wet dry is almost always the way to go especially for high bio loads.
Where is the pump located on this?
Its going to be an external pump on the intake side. For now anyways. The pump may work better pulling through the filter than pushing through the filter so some experimenting will have to be done.
Thanks for the link too. That will help out great!
