from my tank to chiller is 7m. so water in & out is about 14m. i have no idea which power head can do the job.
by the way thanks for reply for my question.
power head with 2000L/H is it ok? im using 1200L/H now. plan to get fox external termostat also.
plan to use pvc pipe or stainless steel pipe for long run.
Is it ok if i place chiller 5-6meter away from my tank? bcoz my tank is inside my room. just want to get rid of noice and heat.
so my in/out hose is more then 10meter. any idea?
