Looking to set up a nano 20 gallon. Mixed corals. What are the best options. Thanks
What has your research been turning up for you [MENTION=22722]Jimsreef[/MENTION] ?
From my past experiences, I have had a standard 20-High rectangular tank, a 12G Aquapod, a 24G Aquapod, and a 29G Biocube. They were all OK and worked well to varying degrees of ease.
The 20-High rectangular tank with a HOT skimmer (I used an AquaC Remora ... no longer made), a HOB filter (a Marineland Bio-wheel with the bi-wheels removed) and extra powerheads, etc. was by far the easiest for me to maintain and work on due to no limitations from the pre-configured sump area that comes with an AIO setup.
The 12G Aquapod is what I feel was the most successful. I had removed the top, turned a portion of the built-in filter area into a refugium, continued to use the Remora HOT skimmer, and had a Viper 70 watt DE Metal Halide fixture on it. That tank did amazingly well and housed primarily a rose BTA, a couple other LPS corals, and a pair of tomato clowns. I miss that tank.
The 24G aquapod and 29G Biocube were meh. I neither loved nor hated them.
I picked up a 24G Aquatop rimless AIO used a few months back and am considering setting it up soon.
Plenty of others out there too if your specifically looking for an AIO.
Success can also be had using a standard non-drilled tank with either HOT equipment and/or a HOT overflow box combined with a small sump.
