Well, actually a vase that holds one gallon of water with apprx. 2 pounds of live rock, as you can see below.

Live rock, two pieces of tonga branch and a corraline-covered frag of green starburst polyps (won at a reef club raffle and covered in bryopsis) is the only filtration. I'm using the Micro-Jet powerhead tuned to 49 gph, the lowest setting. It creates a nice slight whirlpool effect and there is not one deadspot in the vase.

Lighting is a desklamp with a 50/50 20 watt PC bulb. The aluminum foil is used to focus more of the light into the vase, as well as not blind me while I work at my computer desk (my office as I'm a web designer/editor and work at home).

Only substrate I'm using is a crushed seashell from my established tank... took a hammer to it, cleaned off the pieces in old tank water, then dropped them in the vase. This is for the sole little hermit crab in there... I also dropped in about 8 shells for him too, adds to the substrate. The glass was too slippery for the crab to manueavor around the bottom--I thought it was the current at first, but turning it off, I saw the crab had as much difficulty moving about.

All in all this tank has cost me about 40 dollars to set up. Reason I'm doing it? One, I'd like to harvest pods in this tank, from my main nano. And two, that so-called frag I got from the raffle was infested with hair algae and in the period of two weeks had covered the entire rock. Wanted to get it out of my ten gallon.

Now for the problems...

Heat, obviously. The powerhead and light increase the heat of the room, but so far it hasn't gotten above 85, and we've had some really hot days lately. I'm not too concerned about this as I won't really be keeping anything special or demanding in here, other than the gsp which I don't really care about.

The powerhead in the winter should keep the water a couple degrees above room temperature, which will be 69 degrees. So we'll be at 73 or so, 75-76 during the day.

Also, cleaning the algae on the glass build-up. As you can see with the shape of the vase, that's going to be quite difficult. Plan is to add an astrea snail once it begins, and my hope is it won't get too bad.

Maintenance: top off every day, obviously, and water change about 6-8 ounces every other day. As this vase is always in my view and I'm always working in some form or other, I'll be able to monitor it frequently.

All in all, I think it's a very cool "lamp," and I'm interested in seeing how it evolves.

hehe sounds fun, I had a little 8oz cube set up with just a mantis, not very practical, but fun, only possible if you have another tank to top off with.Maybe just get an interesting invert and stick them in there.
good luck with it.

I've heard mantis shrimp can bust glass... I'd love to hear more about your experience with the dreaded mantis, heh heh.

I think a mantis would be awesome in this vase, as long as I wouldn't have to worry about punching through glass.

Most mantis are fine, if you get the little ones I wouldnt worry about it at all. Its the big ones that have the really nasty tendencies. IF you do get one I would put a substrate in and some rock ruble for it to hide in.

I like the look of the tank, the powerhead looks sweet imo in the last picture.
Thats some strong light, 20 watts per gallon ;).



what made you make it all of a sudden, for the pods?


Good luck

Thanks guys.

OCC, I got the idea for trying to culture pods like from a hey, why not kind of moment. I wanted to put a scrubber in the vase, but it looked way too GHETT-O. Instead going to pour a bottle from a shipment of pods when I order another round.

With the lighting... It's probably only getting about 5-6 wpg, as the bulb is vertically placed and a lot of light is lost through reflection, refraction of the curved glass, etc. But the light makes it look really cool, especially the actinic.

The polyps are all coming out today, and they look great. Took a scrubber to the rock and knocked off most of the green nasty, can finally see the purple mat again.

10/12/05 Update with new pics.







Isn't the GSP on the purple rock a piece of crap? The lush bright green gsp came from my main nano. I fragged it by placing a seashell next to the mother mat, and over the course of a few months it completely covered it. Removing it was much more simple than I had made it out to be--I just used a small pair of sciossors and went into the tank during the night with a flashlight. Cut away easily, and by the next morning the polyps were out and looking as good as ever.

The brown button polyps were fragged the same way.

Oh, I do not recommend Holdfast bonding putty. Garbage. I tried four times to get the shells to stick to their new substrate, and each time it didn't work. It was a mess and a waste of time--I just wedged the shells onto the rocks as best as I could. In time, the encrusting mat will jump to the main rocks.

a quick hint, the holdfast stuff only works well if it is allowed to attach and dry while mostly out of water(5 minutes usually does it). Things look really nice in there, again I am tempted to start up a nano.

good god that is so sweet, one gallon. my god, that must be so hard to keep
Amazingly, it's quite simple. Probably due to the stocking... one hermit crab and one astrea snail. GSP and zoos are the only "show" pieces in it. Hardest thing is cleaning out the powerhead once a month or so or when it jams. Every 2 days I do exactly one cup of a water change.

Evap is bad. You have to fill it every day. I have a line marked at the waterline though so it's not so bad, I do it in the morning.
