I need to buy a new heater for my 55 gallon. Don't care about price as long as its below $150ish. I was looking at hydor inline heater (already have a reactor 1000 hooked up so plumbing is no prob) but also like some of the heaters that are digital. My current heater is slowly loosing some of the black marks in it and just want to replace with a high end one. Any you would suggest as "the best" thx
