Thanks for the heads up, raven. I think I'm done with the Fluval Edge as a high tech tank though, it's too much work for such a small tank.
Thoughts on the Fluval Edge 6 gallon -
This tank has what I like to call, the "Dr. Jekyll and Mr.Hyde" syndrome.
Don't get me wrong, I think the Fluval Edge is a great tank for a high tech set-up, if you don't mind the work that is.
One of the best feature of the tank is it's enclosed top, the Co2 is trap under the glass and you can get great diffusion regardless of diffuser. The over powered Aqua Clear 20 is rated for 10 - 20 gallon of water so with a 6 gallon tank, you can imagine how great the flow is.
Unlike my ADA 60P, the drop checker will be dark green in the morning so you know the filter is great as a secondary air stone.But forget about drop checkers, unless you got the hundred dollar ADA one. All those asian drop checkers you see being sold for 10 dollars are the worst kind.
Annnd.... now the bad-
Corner algae, impossible to clean with a scrubber, and by impossible, I mean, too tedious and I'm too lazy.
The physical shape of the hood blocks off the light coverage forcing the hobbyist to come up with other solutions.
