True that!! I do face the inevitable though in that once this temp sensor dies I cannot get another..they last a few years. I have 2 or 3 DA ELites and a few DA lite...I still have a new itemp sensr for the lite as well, tons of PC-4's, SL1's, SL2's Hubs, lol...I can run a lot of tanks..I ran both 230's off 1 ELite unit..was wicked. Made my own bus cables because they only made 6'.Nothing wrong with that. Ive been researching control for my sb reef 16 basics as theres nothing wrong with them, but i have 3 now, so simple wall timers suddenly got a bit more cumbersome.
