I just got an amazing Pico tank from a friend in Chelsea. It has a perfect stand, I would say the tank is 16"x16"x16" (?), 20(+)gallon-ish. I need help figuring out how the back of this tank will be set up.. Here are some miscellaneous specs.. - Back of tank has about 6-8" of space, divided into three sections - Looking to get a VorTec Controller and wavemaker from same friend - Venturi Rio+ 800 connected to return pipe on the right side - Kessil A80 - 3lbs of Miracle Mud - 5lbs of Rubble Zone rubble rock - 250 mL of Purigen - 1L of PhosGuard - Unused activated carbon bag that came with my AquaClear70 awhile ago that I never used - LiveAquaria Reef Salt (Up to new suggestions? Work okay so far) - No media bags yet for either of the above synthetic polymers (Need help with micron size for Purigen? I have tried the bag that comes with the Purigen and they suck) -Quality heater that the guy pitched in - 5 lbs. live rock from my big 35 gal - Big three part stand about 10" high to stage 3-step filtration? Goes in the middle chamber I am looking for an all natural approach. I need some help I am thinking Miracle Mud on far left side (2"-3"), Eggcrate, Rubble Rock. Rubble rock stuffed in the middle, and then the heater and return pump on the far right. But what about the chemical filtration? Where do I put it?
