How would you go about it? I'm half considering a second spec, and I'm currently redoing my first one.

Very cool idea.

2G Fluval Spec ~ fauna and flora in the works!
That would make it just like an underground spring. Fine idea!

I started mock assembly yesterday. I'll snap some photos today, post in the DIY section and place a link here. Due to family life, work, house work, etc. I tend to do stuff at a glacial pace.

umdterps96 makes me wish I bought the spec instead.

umdterps96 Mine has been working great. Betta loves it. I even planted the sponge filter section. Only thing I would change is use or paint black piping for the down tube so it doesn't show. My clear tube turned white

rickey Now that this tank has been running for a few month how did this workout
I dump the pump on mind and drive the filter with a lift tube and air pump But may try this

wintermute After buying 1/2" PVC pipes and fittings from the big box hardware store, I saw that the local store carried 1/2" CPVC - which looks like it will work better for this application - 1/2" ID/ 3/4" OD slides snuggly into the CPVC fittings and slides over the pump's outlet nozzle with just a little work. CPVC has the added benefit of having a significantly smaller outer diameter than PVC, making it easier to hide in your gravel.

Just wanted to share that with anyone else who might be taking on this project.

wintermute Just wondering how the OP's system is doing - any loss of flow issues over time due to bugs benefiting from the partially aerated substrate? This may be pure genius. I just bought a Spec V and want to try this out - although some additional means of surface movement may be required for "normal" fishes.

Also, I assume the best substrate to use is an inert, no-fines, substrate...either gravel or sand (but which is prefered)?

You can do it but the roots may eventually get in the tubing and clog it

umdterps96 Ideally you could cut a hole at the bottom of the back wall and run the tuning straight through. The problem is how tight everything is. I don't have any tools that would have made that possible

It has been running for a couple of weeks now. My Betta is very happy with the low flow and the tank remains clean. I wish I would have taken pics before adding the gravel but you can see the tubing running straight down and a happy Betta
That looks great. I was going to suggest what you did, use some old filter parts for a tight elbow. They are hard to find at a hardware store that are as small, especially with a tight radius.

Not being familiar with the sump part of the spec (seen a lot of them, never owned one), would it be possible to turn the pump sideways so you could run the tubing behind the back plastic? That would be really clean looking.

Basil Wow now that's a nice scape. Love the betta too.

Spec- With reverse UGF ?

It's flexible clear tubing. I just let it coil into a circle naturally before adding the gravel. Works great.

Excellent! How'd you structure the underneath?

As in the shape?
