Avi, I'm afraid I can't help you here because I never used it, but wanted to thank you for sharing the link.
That looks to be a Peltier chiller. Am never too hot for DIY, but DIY might make sense for hard-to-get (locally) stuff like these -- so here's a DIY link you may find useful http://www.nano-reef.com/forums/index.php?showtopic=63061&st=0
BTW, as you know well, nano tanks are notorious for rapid rise and fall in water temperature depending on changes in ambient temperature. Keeping the tank in an AC room might help but if AC is not going to run continuously, then the tank should ideally be made of relatively thick glass with a cover and there should be minimal surface agitation. |

| Avi, small chillers for nano aquariums are available here in Chennai. Hard to comment on the reliability, as I haven't come across any user. |

Even if you do not use such products how do you keep your *nano* tanks cool during summer?
|
By using Cooling Fans. |

Hey Avi,
I don't know about micro chiller but this is what I will try (my simple cheapest DIY) this year. I will get a thermocol box. Stuff some ice from the freezer in a polyhene bag and put the bag inside the box. Drill a hole in the box. Insert a small pipe and put the other end of the pipe to an overhead pump. The idea is that the overhead pump will circulate cool/cold air drawn from the box. I don't know how it will work, but I think it can be a temporary stop gap arrangement atleast. No operating cost except for replenishing the ice every day. May be one can cover the ice in saw dust too! |

Thanks Arnab, Shankar, Rocky and Bappa for all your replies.
@Arnab: May be I shall try the DIY, if I cant get someone to get the same for me. I am not much of a DIY.
@Shankar: Are those local made stuff or similar ones from abroad?
@Rocky: Do you mean freshwater nano tank like shrimp tanks? You can actually use just cooling fans in nano *reef* tank in a non-AC room? What about specific gravity fluctuation everyday?
@Bappa: All the best for your DIY. Only you may have to keep filling ice 3-4 times a day. How about getting those ice boxes (insulated ice carriers for outdoors etc) and drilling holes in them? |

Thats what I intend to graduate to once I try this for a few days and if I see some success. The problem is chillers are very expensive and it really hurts to spend so much for a small tank. That is why I want to try something 'innovative'  |

Avi, the chillers I saw were Chinese - Dophin brand.
Bmukh, I had tried the DIY chiller, what you have mentioned. Will find and post the link. |

As I told you before, small CPU fans are the best way to keep the tank cool during summer. In Gurgaon, weather is too dry and evaporation rate will be very high. So CPU fans are the cheapest and easiest way. Last year I have tried and got very good result. |

Two endorsements in two consecutive days on the same product.
By the way, adding salt helps prolonging the melting of ice. That was mentioned, I guess.
PS: Use LFS Announcements, if you wish to promote commercial websites. No offense meant.  |

Greetings,
I'd like to share my experiences of chilling a 24g nano.
Uk temperatures reach a max of about 35c during the best of summer days, this can cause a rise of 4c over the period of 24hrs.
Whilst I appreciate that conditions across India vary considerably from that of the UK, the core concepts still apply IMHO.
Having fans is a great first step and works well to a limit. Evaporation is the issue.
Peltier based chillers would be of little use in a hot climate as thier effectiveness is based on differential from ambient temperature. They are also highly ineffecient in their use of energy, hence relatively expensive to run.
A better solution would be to use a compressor based nano chiller, take a look at something along the following lines:
http://www.jbjchillers.com/index1.html
at 1/15hp these work an absolute treat on nano's.
The challenge is to find an equivalent unit that is produced in India.
and for all temp control, be it heating or cooling, ALWAYS run an independant controller. something along the lines of:
http://cgi.ebay.co.uk/ATC-800-DIGITAL-TEMPERATURE-CONTROLLER-PACKAGE-1_W0QQitemZ330305670218QQcmdZViewItemQQptZUK_Pet_Supplies_Fish?hash=item330305670218&_trksid=p3286.c0.m14&_trkparms=72%3A1688%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318
if you keep an eye on ebay, PID Controllers and temp controllers these can often be picked up for a little as rs800!
hope you find this of some value
regards
