Hi i may sound hijacking this thread but i have exactly the same situation as OP, so rather than starting new i might as well ask here. My question is for temperature, whats the range i should aim for? My current running empty tank is about 78-82 F, never go any higher than 82 Should i get a compressor chiller? Ive heard that for fowlr temp can go as high as 85F? Also whats the difference between exposed UV light and coralife UV light? What i meant by exposed is the UV light just put onto your sump Sent from Singapore Reef Club mobile app
