the water movement is just an airpump with dual airstone outputs
this creates unique chemistry in the micro reef by constantly degassing CO2 and upholding the pH, I have better water params than most large tanks due to this design.
the system is evaporation restricted, truly, so I can go up to 6 days without a topoff if needed at a swing of .023 to .0245 which is tolerable for my adapted system. the system uses no auto topoff, and with no powerheads, my fail points are highly reduced compared to larger systems.
Having no fish means every time I leave on vacation, when I get back I know the reef will still be alive (nothing to die in the rockwork and rot for 4 days)
it looks strange but there are hidden tricks in the reef that make it last indefinately, a lot longer than many huge tanks. Ill take a maco shot of the inside pretty soon to show the inward projections of the two sps
yes I will crack it open one day but the goal was to test longevity
as this sps patch blocks out the entire front view, I'll spin the bowl around, frag out the corals, add some more chalices and NPS probably and feature the other side of the bowl for a few more years until its totally grown in.
then, crack the vase carefully and have a reef encased in living SPS the shape of a real vase, tell me if that will be sick and unique man

the tank will be upgraded to a 3 gallon system and this vase shaped SPS microcosm will sit right in the middle
