Resun CL 650 vs Atman CS400

[sithspawn]

Which is proven better for a 600 liter tank? Real world not just looking at the specs. Any comments? Thanks.

600 litre tank? You'll need someting more powerful. The CL650 that I had was able to chill my tank with frequent and long chilling periods. In short, end of the month, my electrical bill rose to about an additional S$80.

Unless you can live with higher electrical bills and frequent trips to bioplast for maintenance, I'd suggest for you to look at 1/3 HP and higher powered chillers for such a big tank.
