Gulls Posted October 11, 2020 Hi all. Am having a 40 gallon display with a 25 gallon sump which includes a refuguim. I have a hailea 150a chiller from my previous tank which I intend to use for this too. Various sites displays different capacity for this chiller. Please advice if it would be enough for this setup Other paramaters to consider 1: ambience temperature : 27_30degrees celcius 2: humidity levels: 80% Quote Share this post Link to post
