My .094 (11.83 oz) pico reef

I was overdue for an update :)

I took this tank down due to a few design flaws.

1 - the airlift tube was too small and prone to clogging with bits of rock / sand.

2 - the narrow tank made for a nice size but too hard to clean.

The little tank has lived in my sump for the past couple of months. I took it out to compare to the new tank which hopefully addresses the short comings of the previous one.

The new tank holds about the same amount of water but utilizes a closed loop for circulation. I will build a DIY inline heater for it. The tank has a much better footprint for aquascaping and the bulkheads enable me to have more options - I can easily add in a sump.

New tank specs - 5.5" long by 2" deep by 3" high. Tank volume 0.1 gallons.

Closed loop / two bulkheads (located in corners) using an Aqualifter pump to provide roughly 3 gallon per hour circulation in tank. Lighting is by a 27W PC desk lamp.

Here are my other larger pico reefs. They consist of three 2.5g tanks all drilled and plumbed into a 12g sump. Additional circulation in tank is provided by 3 Mini Tunze pumps controlled by a Red Sea Pro wavemaker. Autotop off is done via a Aqualifter pump controlled by a dual float switch. Skimmer is a Deltec MCE600. Sump also contains a Phosban reactor and some additional live rock rubble. Heating/cooling is from an external Azoo thermoelectric heater/chiller.

Lighting used from left to right (2x13w,1x18w,1x18w) all PC.

The 2.5g's are all from a 2.5g I started for a contest on another website. That was about a year or so ago. The middle tank is the newest, the left is the oldest having been setup from the contest tank. Right tank is just a few months newer than the left. Each tank contains 1 fish, different kinds of hardy damsels. Left tank has a Yellow Belly Blue Damsel (Pomacentrus auriventris), the center has a Talbot Damsel (Chrysiptera talboti) and the far right has a Three Striped Damsel (Dascyllus aruanus). Corals are a mixed reef - everything from mushrooms to various types of montipora. Fish will eventually go into my sump on a larger tank when they get too large. My kids like the small tanks since they are at their height and they can see everything close up.

very cool tanks Melbourne! I think the 3 2.5g tanks all plumbed together with the same sump is a very cool idea! Great work!
 
Melbourne, any shots of the plumbing? I actually had thought of doing something like this before, and lighting like 4 of them in a row with a Tek Fixture or something... but wasnt sure if those 2.5 tanks could be drilled. A look at your plumbing would be helpful :)
 
Thanks - I'll try and take some pictures this weekend of the plumbing. To drill the 2.5g tanks you just need to go slow and build a template since the glass is very thin. I drilled each tank with one 1/2" bulkhead and use over the tank returns. For the .1 g tank I used model airplane fuel line bulkheads since anything else would be too large.
 
You could always do like I did with the substrate and epoxy it to the bottom of the tank. Very nice, love the thinking outside the box.
 
Here are pics of the common sump setup as requested.

Not much to report on the .1g pico tank. Compared to the airlift design I get much less evaporation on this tank. I've only had to top off a tiny amount of water once so far.
