Chiller not kicking out :(

[jem]

just switched my lightings from a PL to 150w yesterday..

and my chiller seems to be working the whole day..

my tank water is 28

my setted temp is 26

using a Resun Cl650

tank volume 4x2x2

heard that it is recommended for this volume of tank..

any help here would be nice

dont think can spend any more money to upgrade another unit

[jem]

any inputs?

[weileong]

When they say recommended for "that volume" you've to see how they tested it?

I believe they run the chiller with "that volume" of water then set it to drop to a certain temp within a certain amount of time. This is w/o any head load taken into account.

Your chiller is too weak to support your tank.

Go for a better one.

haix..no money already leh..

and this chiller is not even a year old..

really saddened

guess i got to live with it..

[weileong]

some pple say their chiller can cool their tank.

some pple with the same chiller say it can't cool their tank.

both tank same net volume.

why? because one tank has lesser heat input than the other.

but only 150W and the chiller cannot support already?

Maybe try to service the chiller.

[jem]

hmm..what do u mean by heat inputs?..

as in the environment?..

does it affect?

servicing?..dont know if its wise to do so..

will warranty cover the service charge?..

thats what i thought so..a 1/4hp chiller cant support 2 x 150w MH?

thanks bro weileong

appreciate the advises

[weileong]

all the pumps, lights, equipments etc etc that you run in your tank adds heat into the water. Your chiller have to work against them.

You try turn off everything and sure the chiller can chill down the water.

I was using my Artica 1/4 HP for my 5 X 2 X 2.5 ft (200 gallons) tank.

I had 2 X 150W MH. Running at least 200W of pumps but my chiller was not on all the time.

I seriously think there is a problem with you chiller.

imo its better to uprated a model abv the recommendation.....

[barnacle]

try and check your air intake filter.....maybe full of dust..

I am using 400W of lighting, one Md40 and one sicce 4000L/hr. no prob with my CL 650 leh...hmmm....maybe you should increase the flowrate of your pump....wat pump your using to run the chilleR?

[lvcap]

I used Resun CL650 on my 3x2x2.5 tank..pumps included rio 32HF and a eheim 1250 for UV and FR..

It couldnt cool down my tank at all! and I dint even switch on my 4x39W T5!

get a better chiller IMO..resun is not as reliable as some other brands out in the market..

End result: i got a daeil 1/3hp and it was able to chill down much faster.

as for some suggestions of changing the pump for the chiller, i tried! many different pumps and none was effective in aiding the chiller.

What temp you set? mine is a 3.5x2x2 at 26 degrees lowest

[zarkon]

Where is your chiller place? In a cabinate? Near the window?

Bro.

U may want to invest in an external theromstat. Helped a lot.

Cheers.

i placed my chiller near the window and right beside the tank cabinet...

my temp is set to 26deg..but it the thermostat shows 28 deg forever!..and never chills till i off the MH..

could it be the cause of faulty calibration?..

sorry guys as i said..cant invest on a better chiller...

money realy running dry..=(
