I'm not tankless any more. You guys can't make fun of me now ;D .. Tank: 12G Aquapod Light: 70W MH Sunpod (piece of crap btw) Controller: AC Jr Heater: Jager 100W Flow: Tunze 6025 and return pump (whatever comes with the tank ) Rock: ~ 5lbs dry rock Sand: ~ 8lbs dry sand Manual topoff - This is the part I don't like. Any recommend auto topoff system for nano tank? No skimmer or fuge. I will keep only softy and macroalgae and maybe LPS. I haven't hook up the ACjr yet. Need to borrow a cable from my friend to program it. I tossed a small piece of shrimp in there to help with the cycle. I won't put any coral or fish in there until I see coraline growing. Last time it took me about 2.5 months. Sorry the water is not clear yet. I shouldn't throw away my biowheel filter : ..
