Hi,
thanks for the advice... any idea what of of external temp controller is it ?? actually my 1/3 HP Artica chiller is oversized for my 4x2.5x2.5 tank.. and it cold down very quickly,, (Within like 20 min, and kick on again..)
Just servied the chiller and internal temp controller is working fine..
maybe as what you said, the flow rate is unsuitable.. i am using ehiem pump with flow rate of about 4000 l/hr is that ok or i should use a lower flow rate ?
thanks for the advice..
