I have this tank I got from a mostly failed Kickstarter. Iíve never housed jellyfish in it because Iím not very confident it wouldnít kill them because the sprayer bar creates this weird back suction that would likely suck in tentacles. While cycling the tank, I watched brine shrimp get sucked into the sprayer bar. I can keep brine shrimp alive in it if I turn the flow rate way down on the pump but in the end, they all usually succumb to the sprayer bar or filter. So Iíve been watching this empty, somewhat cycled saltwater tank for months and Iím not sure what I could house in it and have them thrive. Iím not very experienced in saltwater or nano tanks so thatís why Iím here, to ask what you would do with this poorly designed mess? Itís 5 gallons. About 3.75-4 gallons visible in the circle part and the rest is segmented and not visible in the filter/pump box.
