Fluval spec V filtration (style)

Could someone please post pics of the filtration system on the fluval spec V. I like how it is all hidden on one end of the tank and would like to try and building something similar but on a 12g or 20g long.

any pics of exacaly how it works would be apreciated.

I think its basically just a tank divider with 2 compartments. One holds the sponge and filter media, the other is for the pump.

its cascading, so there is an overflow into the media section, the first compartment, and then it either overflows, or fills from the bottom into the pump section. so both have water. its basically an overflow box if you want to google how those work.

**I personally don't have one, so if anyone else with actual experience needs to correct me, please do.

You're basically correct on the overflow, but there is also a small intake a few inches above the bottom on the media side. I'm not sure why the intake is there, because the overflow would work just fine without it. My tank is a Spec V, I'm not sure about the original Spec.

I'm thinking of the spec v. I was debating getting one but I think it would be cool to build a bigger version of a similar design. Could you snap a pic of your overflow/filter area?

You could look at this thread to get an idea. It's the same style as the Spec V and has some good shots of the tank and filter area: http://www.flowerhorncraze.com/topic...apa-county-40/

If you are looking for an AIO for a 20 long you could take a look at the one by one of the sponsers on nanoreef.com.

The only thing I dislike about the filter on my spec is that the water in the pump compartment stays pretty stagnant. So when I don't have my breeder box hooked up I run an air pump in there to get the water moving. Also I plugged the small hole near the bottom. If I had to guess they made that as a fail-safe in case the water level gets so low it doesn't reach the overflow part.

I don't know how the water in the pump section would get stagnant since water is constantly flowing through there at 70 or 80 gph. Unless you mean that there is no surface movement, which really shouldn't matter since the water has already been filtered.

I stuffed a heater into my pump compartment, and then I cut a ~1/4" hole in the outflow line to keep the water level higher in the pump compartment for the heater. There is definitely no stagnation in that chamber on mine, even when I turn the flow all the way down (which is how I will likely keep it).

That hole near the bottom is to keep water flowing to the pump in case the water evaporates too fast and the water line gets below the intake grating on top. Because of the hole in the lid, if you heat the water much warmer than room temperature (our house is cold in winter so water is about 8 degrees warmer than room) water can evaporate really quicky. At least with the little hole at the bottome your pump doesn't run dry and burn out.
