Hi bro. Yes, I do take all these in to consideration. Since the chiller can support up to 30l, so I thought why not give it a try for my new fowl tank. I only want my temp to go down to below 30, cause my room temp can go all the way up to 33 even with the cooling fan. Anyway, the water flowing out from the chiller is not even cold at all. So I suspect the chiller might be faulty. Thanks for your advice! [emoji1]
