Mummer Posted July 26, 2005 Share Posted July 26, 2005 This question applies to 12 gallon Nano Cubes and assumes one pump only. We all know that various corals are typically rated as requiring low, medium or high flow (or some range therein). Has anyone looked at what GPH rates would satisfy each level? For example, would a flow of 150 GPH be considered low, medium or high? What would the minimum GPH rate be to be considered medium, and what rate to be considered high? Link to comment
phergus_25 Posted July 26, 2005 Share Posted July 26, 2005 It all depends on the ammount of water it is in. Link to comment
xdannyx_ Posted July 26, 2005 Share Posted July 26, 2005 yah. 5 gph would kick a .1 gallon tank's arse Link to comment
ricky1414 Posted July 26, 2005 Share Posted July 26, 2005 DO NOT TURN YOUR TANK OVER BECAUSE ALL THE WATER WILL SPILL OUT!!!!!! J/K... I feel that gph is like light intensity. It's not the watts per gallon, or gallons per hour. If I may- I can have a calm tank with a coral being blasted by a powerhead, and it would be good neither for the tank as a whole, or the coral subject to the blasting. I would take a few powerheads and place them around inorder to have currents, or water movement that sates them all. See how the coral reacts to the water movement, and adjust accordingly. It is just my opinion, but I hope it helps. Link to comment
Casabubu Posted July 26, 2005 Share Posted July 26, 2005 exactly... you could have a 1000 gallon tank with a 50 gph pump as long as the coral is right next to the outlet of that 50 gph pump. Link to comment
mdt178 Posted July 28, 2005 Share Posted July 28, 2005 The amount of rock and its layout also affect the flow. SPS sticks and soft corals will cut the flow even more. Link to comment
