  1. General Reef Discussion
    hi i have a 29 Gallon, installed a tunze reefpack 200 two days ago and i have a koralia 1 and k2 in the tank. 40lbs of LR and im not sure if they need more oxygen in the water. tank is open top. my last filter/system added a bit of oxygen to the system and this new setup produces no oxygen...
