Chiller connection.

Hi all,

I am intending to purchase a chiller. However, I need some feed back on the setup.

My tank is a 5 x 2 x 2 tank. Is it true that I need one of my canister's output flow to be connected to the chiller? I am intending to get the Resun CL 650 which I believe would be sufficient for my tank's size.

Would having a CL650 take a shorter time in cooling down the tank coupled with the output flow of the canister filter?

Also, can it be independently connected without any output from the canister filter attached to the chiller?

P/S: hope I am not confusing anyone here with this setup.

chillers do not have the capability of pumping water as they only cool the water. you'll need to connect either a pump or a canister filter to the chiller to pump the water.
hope this clears some of your doubts.

I was told that a CL650 is just nice for a 4x2x2ft tank. You might want to look into a CL500.

I was told CL480 is just nice for 4x2x2....

if u can afford, the bigger the better.....why?
it cools the waterdown faster-->run less times/hr-->save $ in longrun

Take note of any other equipments that will induce heat, i.e lights, pump, etc.

Think its a gd idea to go one level higher on chiller selection. You'll not want to find out that the chiller is underpower after u bought it.

I'm using C0500 for my 5 x 2 x 2.5ft.

Yo bro,

That's true. However, isn't CL650 sufficient for a 5 x 2 x 2? How much is the chiller that you purchased?

**solonavi** · 2nd Mar 2006, 10:57

Its ard $500.

C500 will serve your better imo. It's seem like a newer model and the design is better in term of look.

**vratenza** · 2nd Mar 2006, 12:52

If u getting C0500.... please take note of the inlet/outlet connection.... it is about 1 inch diameter....not plug an play like the cl650...... so need to figure how to fit ur 16/22 hose there....

See my blog for my solution....just one of the many solutions available

Also note the required flowrate for any chiller you purchase, and make sure your filter/pumps can meet the requirements. This is to ensure that the chiller operates at optimum conditions... and thus save you money for electrical bill.

As chillers have high resistance, get a pump/filter that exceeds the minimum flowrate somewhat. Also the final flowrate entering your tank will be significantly lower then the pump/filter's specifications, so your tank circulation will be affected.

Make sure water going into the chiller is pre-filtered. That means filter is always before the chiller. Or, if using a dedicated pump, there should a mechanical prefilter. You don't want any debris getting into the chiller and cloggin it up... it's not easy to clean them.

Also reverse-flush the chiller every few months or so... this recommendation should be in the manual. For this purpose, figure out a way to make it as simple as possible.

Would a 2400L/hr external pump be ok? Just to ask, how much is an external pump going to cost me? Same price as that of a Chiller also?

**solonavi** · 2nd Mar 2006, 16:53

A decent brand one will cost $200. U can try if there is any re-used one.

Check the chiller requirements... there is usually a maximum and minimum flowrate. If it's too fast, it's not effective either.

From Resun's specs, minimum is 800L/hr and optimum is 2400L/hr (they placed it as Best! for that rate) but i fancy its really fast... 2400L/hr.. that will cycle my tank 5 times in an hour.

**vinz** · 2nd Mar 2006, 17:54

I was running something like that for my chiller in a 6x2x2. Tag your CO2 to that circuit too and then run a rainbar across the lower back of your tank, pointing forwards. For that flowrate in a planted tank, you definitely cannot use a single normal outlet.

**vratenza** · 2nd Mar 2006, 23:35

funny thing is for c0500, they only specify min 500gph or about 2000Lph, din mention the max or optimum.......
fyi, i got myself a used Eheim 1260 to run my c0500...cost me only $100...intending to set up a closed loop chiller/c02 circuit....with sponge pre-filter and rain bar output.....will be setting it up over the weekend...will post some pix in my blog once its done

**hii** · 7th Mar 2006, 15:21

my CL650 running on 5 X 2 X 2 can manage at 25C. chilling time about 1 hrs .. so C0500 will be better lor ...

**grey_fox** · 8th Mar 2006, 12:12

Haiz more $$ gonna fly away.

**grey_fox** · 10th Mar 2006, 19:47

OK, just got myself a 2000L/hr internal water pump. Just a question, should I use another spray bar or just a dual water flow output?

Also should I have the CO2 reactor (probably need to build a DIY external reactor or buy one) attached to it?
