Help with chiller

[deadmanz]

Hi bros, Im planning to get a Resun CL650 for my 3ft tank... but the issue is... Resun chiller recommended flowrate is at least 1800gph... but my cannister is rate at around 1550gph... would like to know if the flowrate is too low and end up lots of kick in? Or should i go for a CL450 instead? Thanks in advance!

Are you planning to upgrade to bigger tank? if not, assuming your tank is 3x1.5x1.5ft, CL650 is overkill. I was using CL-280 for 3ft tank, CL450 probably better option. Alternatively you can modify it using external sensor.
