Just sharing my DIY chiller using 800ml Blueice (NTUC) for my 1 feet tanks Nanotank.
Had try and tested and manage to reduce the tank water temperature to 23 degree, and lasted more than 5 hour before the temperate slowly increase. My tank is place near to my window, so during afternoon, the temperature previously is about 30 degree. With this set up, manage to hold the temperature constant at 23 degree from 11am till 4pm.
My tower fan is set to operate at 5pm till 9am. Which will make the tank temperature around 24-25 degree.
Hence, during evening time, I just pop the Blueice back into the freezer and next day will be back for operation.
Do feel free to contact me if there's any query.
I would to glad if you have any feedback to improve the design.
Thanks.
Yeah... Been re-freezing the blue ice daily.... But not a lot of work.
The pump I using is a 5W pump, so the temperature change in the tank is very slow....
Plus my tank temperature in the morning is around 25 degree... So not much of drastic change in temperature...
Had a pail of 30 Litre treated aged water, so I just scoop some water and top the tank daily....
Manage to decrease the death rate for my CRS to Zero since February. Hahaha....
1/4" Stainless Steel Tubing 6metre long @ $30
Lol... I've my pend bender and I bend it myself.....
Wow in that case it seems to be stable and a very cost effective compared to buying a chiller for a nano tank! well though plan
Save Electricity Bill..!! Hahaa...
I share this information so every hobbyist can save money....
This idea might work for 2 feet tank also... Maybe need more coil turn to increase the heat transfer...

This is the bender... A manual bender.... But actually 1/4" Stainless Steel Tubing is very thin... Hence, you could also bend it easily with your bare hand.
I've research and thought about replace my Blueice with a Peltier or TEC, (Thermoelectric effect).
Drop by Sim Lim Tower on Thursday, and saw a Peltier 12VDC, 60W @ $25.00 (Level 4).
Due to budget constrain, my wife display a "RED LIGHT" and stop me from purchasing it. Sad!
peltier cooling has been discuss before , doesnt work that well , if you intend to use electricity power might as well use a chiller off the shelveOriginally Posted by IrvineChen
, that bender wanted to buy it last time but didnt, i thought it only meant for copper pipes, any good tips for bending ?
My bender is for stainless steel purpose... Bought it for $85 at Able Hydraulic Pte Ltd at 50 Tuas Avenue 11.
Tips for bending piping, is to mark the point that you wan to bend, and slot the marking into the bender and bend(Quite easy).
Peliter consume lesser electricity as it's DC... A chiller is AC input.... Laptop power input is 12VDC, 65W. I would say the electrical bill wouldn't be more than $20 a month.
However, still pending for authorization from my wife for permission to test out my experiment... Whahaha...
Is it just the Thermoelectric Cooler Peltier 12V 60W for $25 or the whole kit for $25?
If it is the whole kit,it is a good buy. Im setting up something similar like yours but due to work and limited time,
the project is on hold.
Hehehee... Glad to heard about it.... Peltier alone onli is $25...
Heatsink $6...
Heatsink + fan $18
Hahaa.... Then I come out with Buget Irvine Chiller for Nanotank..... Lol...
Should be able to work with a nano setup with peltier temperature controller. I believe if use with a nano tank to drop by 4-5c from ambient, peltier cooling with controller is efficient enough. I will share my work once my stuffs arrives.
Great.... Thanks Greenie! Looking forward for your information....
If it work, I can convince my wife with it....
you order the peltier through ebay?
I ordered the parts all from ebay and cost me about S$80+. For the heat sink & fan, I have left over parts from my PC builds.
No problem, with this project, I'm learning and hope to share. But I will open my own thread, hopefully soon. As those who deal at ebay, sometimes stuff only arrive after 4 weeks.
