Thanks Jesse, and luckily for me the guy who had the tank before me had drilled four 1.5" holes across the bottom which he used for a closed loop system for salt; which I can use for a recirc pump and maybe a couple of Lifegard heater modules; that way my filters are still getting dosed at the proper rate and I will have good flow through the tank to eliminate deadspots; Thanks for your help, Jeff. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
