How long yr chiller uns each time

[UFO]

hi there,

i bot a 2nd hand chiller 1/3 hp without brand, think is made in M'sia. i'm using 2 x 20k mh light on a 4ft tank. i set my chiller at 26 degree. notice it runs for average 30mins every 1 hr. i think my water heat up very fast not only b'cos of the MH, but also due to using too many PH. 1 for chiller, 1 for skimmer, 2 for water return from sump & 1 for circulation in tank.

so will like to know for those who is using chiller, how long yr chiller runs.

thks very much.

at what temperature does your chiller start to chill again?

I think ur chiller is too small for your tank.. that's why

mine runs like 3 times a day for 15mins each time... but i maintain my 2 ft tank with a 1/4HP at 28deg C with a DIY temperature controller with external probe to get more exact readings. Used to be running 5mins every 1 hour, but the controller did helped.. but in your case, your chiller could be too small for ya tank..

Using 1/4hp for 90 gal tank.1 mh150w 3ph

runs 15-20min cut off for about 1 hr (mh on) 11/2hr (night w/o mh)

my teco TW6 runs non-stop when the 2x250w MH lights up and is able to maintain the temp at 26 degs (set point 25 degs) for my tank 4ftx2ftx2.5ft.

Once MH off it runs another one hr to bring the temp down to 25 deg. Then compressor off and another 3-4 hrs later run another hr.

If this is too small then I need to upgrade to 1.25hp already.
