I have a new Red Sea 500 Peninsula (105 gal Dt + 32 gal sump) which has finished cycling. I currently have one Ehiem heater which is working perfectly but looking long term where to invest $$ for better equipment. Looking at this: https://www.bulkreefsupply.com/600w-titanium-aquarium-heater-system-wifi-bulk-reef-supply.html. Is this a good/necessary investment for piece of mind? What do I really need for a bulletproof heating solution?
