I keep the room tem in the mid 70's..
And I am planning on using lower wattage MH
.. 175's but Ill likely have some supplemental lighting.. VHO
would be the hottest of my options.. T-5 HO
the coolest but that might be oppinon.. I might OD some T-8's for 03
.. Im likely going with 10,000K on the MH
.. it will be a LPS
tank.. they done make 6500K in 175 MH
.. or I would consider those..
as far as pumps go.. the pump for the sump will be small.. the closed loop pump will be the big one.. once I deside on how much flow total to go with.. that should be a less heat situaltion..
So it might be best to set it up and see how much the temp swings before livestock is put in to gauge how big the heater(s) need to be? TIA
