optimum speed for pump = chiller to cool tank

[Creetin]

wats e best speed? i using a 1300l/hr pump and mi tank is a 2.5ft by 18 inch. water volume not more than 38G.

the chiller, a 0.25HP, takes like an hour or so to get e temp down from 28c to 26c.

i reckon it can be faster - could it be due to:

1. water flow too fast?

2. not enuff gas?

I always thought it depended on what type of chiller you are using etc.

[Creetin]

but if water flow too fast the chiller cant chill properly i tink?

Mine's jus a 2 footer, using resun cl450. Takes me jus 2-3 minutes to cool temp from 28-26, not using any pump, jus my cannister pumping the water through the chiller. Water circulation is enough for my tank cos i got another additional powerhead creating currents. But then again, my tank is jus 2 feet and my chiller is more suited for 3-4 footers. but 1 hour for 2.5 ft is a little long rite?

but having a big change in temp in such a short time... u r going to stress your LS.... even it's just 1 dregee diff...

mabbe that is too fast? but my 1 plus hr surely too long rite? oni 2.5ft leh.

Dunno leh, my thermometer in tank states jus 26-27 degrees, and the cooler activates once every 3 hours or so...jus that the cooler activates at 28 though my thermometer in tank still around 27... so i dun think its that bad rite? hmmm... i hope not...

oops! creetin, sorry for gatecrashing your thread...
