Hi everyone,

After a two years hiatus from fishkeeping, I decided to start getting back into it again. My previous tank was an ADA Mini-M iwagumi:

Image


I picked up a 12 gallon Fluval Edge on impulse while browsing a LFS. The plan was to go low-tech and low-maintenance. Since I'm going with the stock LED light, this will be a low-light tank. However, I'll be using an Eheim 2211 canister filter that I had instead of the included Aquaclear HOB. The 2211 will be connected using some Cal Aqua Lab lily pipes and heated with a Hydor in-line heater.

Substrate:

The hardscape consists of one large Manzanita driftwood and ADA Seiryu stones.

Since this will be low-light, I decided to go with trident java fern as the main plant.

Image


The tank will be fertilized every 2-3 days with Pfertz fertilizers that I had from before along with Flourish Excel.

The tank after planting and water added:

Pipes and filter:

After cycling, the first fishes added (also currently the only fishes) is a school of Corydoras habrosus

This is where the tank is at right now. The scape should look better when the java fern greens up and fills in more. I plan to add a few more stones to the front area and some more Mini Christmas moss.

The next livestock to go in will be a shoal of CPDs (my favorite fishes to keep) and a bunch of crystal shrimps.

I'll continue to update this thread with the progress.

Thanks for reading. All comments are appreciated!

Looks good, I used have a12g edge for a little over a year and now it's just sitting in the garage...I attempted to do a low tech recently but that went to waste...I just hated the small opening on mine...took the top off, but still, the tall and narrow tank makes it so hard to scape it or stock it properly...
Good luck with yours !

Yep, that little opening is a pain. Although, the good thing about it is it pretty much eliminates livestock deaths by jumping. I've lost so many jumpers in my last tanks because they were topless and rimless.

looks great! the scape is really cool and the dw works perfectly in the tall tank :D
Thank you! I'm just glad the driftwood fits into the opening.

Nince minimalistic hardscape. The pictures with the DSLR show the texture so much better. I like how the round rocks complement the roughness of the manzanita. The java fern should fill the back nicely.Do you plan on adding a carpet plant ?

I hear the Amanos will change their colour depending on diet, so maybe they were fed something with a blue pigment.
I see a window on the right side.Do you keep the blinds open ? How much sunlight does it receive ?

I decided against a carpet in this tank because of the Edge's light. It's pretty much a spotlight that only focuses on the center of the tank, so the corners and sides will be very dim. I didn't want to add another fixture because that will ruin the tank aesthetics.

I hear the Amanos will change their colour depending on diet, so maybe they were fed something with a blue pigment.
The blue color turned out to be only temporary from the stress of being transported from the LFS. They've now returned to the regular clear/white color.

I see a window on the right side. Do you keep the blinds open ? How much sunlight does it receive ?
I keep the blinds on that window 90% closed all the time because of algae and also because of the TV. Otherwise, it is south facing and the tank will be an algae farm in no time.

Thanks for reading!

Looking good! No plans for a moss wall? That'd go well with the height of your tank. If you keep it trimmed around the inlet you should have no problems with moss entering your filter.

Tropica 's videos almost convince me of trying a moss wall with the 12G fluval edge I have sitting in the garage.

If I ever attempt a moss wall, it'll have to be mini Xmas moss. Grows even slower than the regular Xmas moss that I have in my tank and stays even shorter, meaning less maintenance and trim work. Plus , your shrimp will love it.

On a whim, I pulled out my Edge and set it up with some left over equipment I had gathered over the years. It's been running for 15 days now and just finished cycling.

Specs:
  • Fluval Edge 12 gal (spray painted silver)
  • Fluval Plant 3.0 Nano light
  • Fluval 207 canister with Aquario Neo Flow inflow/outflow and Hydor ETH inline heater
  • Livestock: 10 pygmy cories, soon to add my 14 CPDs
  • Plants: Anubias (mini, jade green, wavy), Java ferns (Windelov, narrow, standard), Hygrophila Pinnatifida, various crypts, Echinodorus quadricostatus, mosses (wheeping and Taiwan)
  • Aquavitro fertilizers (Propel, Activate, Synthesis, Envy), Flourish root tabs, Excel, no CO2

The tank has been running for 3.5 weeks now. I’ve added some more plants (Anubias kirin and pinto). The initial melting from emersed to submerged is done. Now just waiting for everything to fill in, especially the mosses and narrow fern which is looking a bit scraggly). Luckily there has been next to no algae so far.

I’m tempted to move my paintball CO2 system to this tank but I have a feeling the closed top of the Edge tanks might have disastrous consequences for the livestock.

For inhabitants, there are 11 Pygmy cories, 19 CPDs, and 10 orange sunkist shrimps.

Love tank resurrections like this.

As long as there's a slight ripple at the center surface and there's some gaseous exchange, they'll be fine. Plenty of people have run Edges with CO2 through the years.

The H. pinnatifida will do a lot better with CO2, as will the other plants, even if you're not running medium or high lighting.
