fluval edge mod

So you've already got an edge? I figured you where going to buy one and since they retail for close to $200 you could easily make a bigger one for half that.

I bought mine when they first came out and they were slightly over priced IMHO @ $179.99...a couple weeks later the priced dropped off to around $139.99 which was more realistic based on what they are... Now I've seen them retail as low as $99.99 which is OK but you still have to spend more to make them a complete system (as advertised) IMO...

On another Local FW forum I've seen them go used in about the $25-75 range.

Aesthetically I think they are awesome looking little systems and I considered make a larger version (45gal'ish) until I talked to a few custom tank builders ($$$)...In the end based on the price and other issue (gas exchange etc.) I figured a cube was more sustainable for my purposes.

Modifying & maintaining them though is a real exciting challenge, I love checking out what people (more on the hitec planted side) have done with them.

Yes $100 would be a good price for the edge as you couldn't really duplicate the whole thing for less but if you're replacing the lights and filtration you're really only using the glass which I'm pretty sure you can get for less than $100. The stand isn't ideal either if you're planing an overflow so IMO you should start from scratch if you're planning a heavy mod project. I wish I started from scratch on mine but I did get the setup for $60 used so it wasn't too bad.

i got a pretty good price from conceptaquariums, for a 120 edge style tank, still not rich enough though, i should focus on one tank at a time lol.

on the note of gas exchange, doesnt a skimmer just plow O2 into the tank? or is the problem CO2, which i could understand being a little more difficult.

Skimmers need O2 in order to create the flanking action which put O2 into the water returning to the tank.

i dont fully follow, are you saying that all the o2 that the skimmer sucks in with the air usually gets bound to the organic compounds and doesn't end up entering the system at all?
