Hello everyone. I need some feedback on somethings. im seting up a 265 gal and plan on useing gravel,a fluval fx-5, a milliniem 3000, and 3-4 powerheads as filtration. Im gonna keep all new world cichlids so what would be best to heat the tank a inline heater or several sumersible heaters secured in pvc. Also i was really thinking of geting a u\v sterilizer clarifier to put on my return line. the guys at the local pond store said that it could kill benificial bacterial as well as the bad stuff. Does any one use one if so what size or should i just scrap the light. I heard it could kill parisites and other bad microstuff any sugestions would be great.
