PJ Reef tank, I'm Skeptical.
 

So I just discovered this guy who is selling a pico reef setup. But it lacks a filter, heater, powerhead? Is this a legit thing that could work? Experienced pico reefers responses please! thanks!

Here's a link to the website.

I'm not an experienced Pico reefer, but would have thought that no circulation at all is a bad thing waiting to happen. Also, his blog hasn't been updated since January 2014.

I saw something like this once, it utilized an air stone for its movement. The tiny tank grew SPS and such well though so it obviously worked. I'd hate that salt spray though - you would have to contain it somehow.

It can be done. I think I could DIY that setup for about $50.00 however. It seems very expensive for what you get.

Yeah, $300 is insane for a jar, light, live rock, and coral frag.

I think it's common to just use an air bubbler for O2, sometimes a heating pad depending on the lights, no filter or power head. Also common to seal the container to prevent evaporation (though I guess you need a little hole to let out the bubbles from the airstone). Some pico reefers dose, some don't, some do really big water changes like 100% every couple weeks.

Brandon Mason linked above has a great reef in a jar that's been thriving for a long time. He posts around here on and off, more on the nano reef forum I think, I forget the actual name of the site.
Mary Arroyo has a beautiful jar too.
