fluval edge mod

sphelps · #1 03-02-2011, 04:24 PM

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?

No a skimmer should put a potion of O2 back into the tank, this is the reason you want a bubble trap after your skimmer to break up any micro bubbles that make it threw you skimmer. Bubble = air pocket, popped air pocket = O2 into water column.

oh yeah of course that makes sense. so what about CO2? i understand it can lower ph if it gets too high, does a skimmer help reduce this, or is the only option for CO2 removal surface exchange. and how much does macro-algae in fuge help with this?
