I am using teco 1/10 with a 1000 pump for a 3 ft tank. It takes 1+ hr to cool down 1 degree. Is this normal? Should I change to a pump with higher flow?

[kksg2000]

Another question can I connect return pump intake to the chiller , so that I run only one pump. My return pump is 5000, too high?

[Clement_jr]

flow rate u have to refer to your manual book, or find them online.

after cooling down to ur desired temp, how long does it takes to run again?

1hr+ seems a little long, and 1/10 seems small as well.

anyway, I do connect my from my return pump via a T-branch.

[kksg2000]

according to the manual, the min flow rate is 500l/hr and 1/10 is for up to 500l. My 3ft tank is < 400l .

My point of view.. always go 1 size above the recommended. I using an oversize 1/3 artica for my 50G appx 300L. Using 15min for cool down and interval of 50 to 1 hrs. Depend on weather as mine are close to a window. I using a T for my set up too. I felt quite save onumy electricity bill. Kicks in and off faster with this 1/3. Just to share my exp

15mins? cool... maybe should change to 1/3..

you can installer a control valve

chiller will kick in more often if you T from return pump then back to sump

cooling time will be faster thou

1/10 is a bit under power for 3ft with sump. I used 1/10hp but changed to 1/4hp for my 2 feet cube. I think it is not advisable to have a high flow rate for the chiller. Maybe you can try 1000L/H. Inflow from sump and outflow to tank.

When the chiller is working, do you feel the hot air outside the cooling fan? If it is not hot at all, then you need to service the unit.

ya I felt hot air outside the cooling fan. i think should upgrade to 1/4 or 1/5...

just found out from teco website .. teco TR 10 is actually 1/8. Mine one should be 1/8 and the flow rate is 500-1000l.

if T from return pump, then chiller outlet should go to DT too.

i did mine this way.

chiller starts to kick in after 0.4-05+ target temperature and stop chillng - 0.4-0.5 below set temperature. e.g. if i set 26, it will chill to 25.5 then stop. is this normal for articia chiller?

[kksg2000]

1/3 is damm fast ... took about just 30+ mins to cool 1 degree for 3ft... compared to my 1/8 teco 1hrs + for 3ft

[kksg2000]

bro any idea what pump flow rate to use for 1/3 chiller?

[Kelvin81]

I using eheim 1260 for my 1/3 artica. You can check the artica website for info. More accurate.

[Clement_jr]

artica webby got put the recommended flow rate. try to match it.

bro does your 1260 hums and create strong vibration noise? I tried to up inside the water, without touching anything, the noise is still there. any idea?

My old 1260 will vibrate a little, need to place it on something soft to reduce the hum. I used those rubber suckers, bought like 6-8 and stuck them on the sump bottom then sit the pump on the rubber stubs, no sound at all after that.
