Hi all, I have always learned that the heater in a 30 gallon should go horizontal about 3 inches above the bottom of the tank. I have a tank set up where that location is less than optimum. I would like to move it to vertical about 5 inches from the wall on the opposite side of the tank from the filter. Seems to me there shouldn't be much difference. Is there any sage reason why the heater should really stay horizontal 3 inches off the bottom? Thanks Shango ________________________________________________________ Shango Los Phone: 206-595-9006 Fax: 206-729-5271 www.ShangoLos.com www.SunbreakShines.com _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
