As you guessed it im wondering if any of you fellow aquarium enthusiasts have used or heard anything about the cobalt neo-therm 150w heaters I was gonna put 2 of them in my 75g since my unknown brand heater is taking on water and probably shocking my fish (im taking it out the tank at lunch today) any feedback will help and if I dont like the heaters or people say they are garbage I can just return them but reason I liked them was because brs (bulk reef supply) gave them a great review and ive heard great things about them from amazon.com reviews also the form factor will fit my 20l refugium im building quite nicely
