nemines Posted January 1, 2008 Report Share Posted January 1, 2008 hi, my nano is getting to 28-30 degrees and i want it at 24-26. do any of you guys know a cheap method of cooling the water for an 80L tank? the tank gets no direct sunlight, however, my room is small and the lighting is probably the culprit. how much would a small chiller cost? any other suggestions? thanks, hugo Quote Link to comment Share on other sites More sharing options...
markoshark Posted January 1, 2008 Report Share Posted January 1, 2008 Fans. You can buy them for pretty cheap, just run them when your lights are on And unplug your heater completely. Quote Link to comment Share on other sites More sharing options...
evilknieval69 Posted January 1, 2008 Report Share Posted January 1, 2008 And unplug your heater completely. No, don't do that! The heater will not come on if the tank temp is over what its set too anyway, but you do risk getting a cold night and the tank temp dropping too far. If your tank is getting hot, unplugging the heater will do nothing but make it even riskier at night time That aside, i agree with marko. Fans are cheapest, but you get heaps of evaporation Quote Link to comment Share on other sites More sharing options...
markoshark Posted January 1, 2008 Report Share Posted January 1, 2008 Fine, i'll rephrase that. Test your hearter by plugging it into a jug of water. Notice that the temperature on the heater is way out? Adjust accordingly. All of the heaters at a petshop I frequent were still on, the shop temp was above 27 degrees. (my Jager was set to 24 degrees. I discovered it was turning off at 27.5) I now have a temperature controller. Running the fans continually, aimed at the water surface, my tank will drop down to 23.8 at around 8am, and then start to climb back up Quote Link to comment Share on other sites More sharing options...

Fmxmatt Posted January 1, 2008 Report Share Posted January 1, 2008 This is what i've done with fans, on a timer they've made a HUGE difference! Quote Link to comment Share on other sites More sharing options...
jolliolli Posted January 1, 2008 Report Share Posted January 1, 2008 I've just bought one of these units, which clip on nicely to the top of the tank. They come with 1 to 6 fans http://cgi.ebay.com/Metal-Halide-Aquari ... dZViewItem Quote Link to comment Share on other sites More sharing options...
Stella Posted January 2, 2008 Report Share Posted January 2, 2008 Fans are great. And because they cool through evaporation it kinda has it's own thermostat: they do more cooling when the temperatures are higher. Also check your thermometers. Aquarium ones are NOTORIOUSLY wrong. The black adhesive ones are even worse. In my experience electronic ones can get worse with age. I have a (sadly borrowed) scientific thermometer which is reliable. My Aqua One digital one is 1.5 degrees wrong. My weather station one is 3 degrees wrong and my chiller is one degree wrong. All hotter than reality. When buying don't just grab one, check them all against them all. Sadly I don't know how to find reliable ones, but I have had dairy or home-brew supplies places suggested to me.

nemines Posted January 2, 2008 Author Report Share Posted January 2, 2008 i've tried two kinds of thermometers and i got the same temp on both. however, my temp doesn't seem to change much at all even when the lights have been off, so i'm beginning to think that maybe my powerheads are heating the water excessively. ive recalibrated my heater and it's working fine now (i tested it in a bucket). how much are chillers? i don't really have much room on top for fans the tank's surface area is 60cmx30cm. i am using an aquaone MG 600 unit and a t5 unit and as we are renting, i can't suspend them over the tank. i've turned off the main power head now and will see if the temp drops, if so ill probably go and buy an eheim 1262 which can sit outside the tank and therefore not heat it. thanks for you help Quote Link to comment Share on other sites More sharing options...
Stella Posted January 2, 2008 Report Share Posted January 2, 2008 I have a 10cm desk fan resting on carefully spaced lids so it can blow in but not fall in (unless I am really careless, like I have been four times so far.... get an RCD switch!) I guess it depends on how your lids work. Even in a rented house you could use some of those removable Command hooks to suspend something like that. Might work for my mudfish tank.....

cookie extreme Posted January 2, 2008 Report Share Posted January 2, 2008 ive recalibrated my heater take it out of the tank and put it in the garage for the next few month!! let your tank temp drop as much as it can. this will counter act any of the powerheads in the tank. why do you run a heater in the summer?

Remember kids, if your tank drops to 22 degrees, its only 3 off the norm, rather than being 5-10 Quote Link to comment Share on other sites More sharing options...

nemines Posted January 2, 2008 Author Report Share Posted January 2, 2008 i wanna try and get as much continuity as possible. IMO i would prefer not to have a temperature fluctuation of over 1*C. i might just save up for a chiller... Quote Link to comment Share on other sites More sharing options...
wasp Posted January 2, 2008 Report Share Posted January 2, 2008 I have a chiller, but can tell you they are expensive to buy, noisy, and expensive to run. We are in peak overheating time of year now. Because a fan is so cheap, it could be a plan to install one NOW at least on a temporary basis, ugly as it may be, just to keep your tank alive. Several of the posts above show some excellent fan setups, I'm impressed guys. And girl. But if you don't want to get too technical at this stage, even an ordinary household fan, purchased at the Warehouse for less than 30 bucks, pointed at the water surface can do a good job.

cookie extreme Posted January 2, 2008 Report Share Posted January 2, 2008 What happens if you get a very cold night or two in auckland? now in the middle of summer? i remove my heaters in the middle of december, give them a good clean and check them out to see if i have to replace any and put them away. tank goes down to 21 - 22 degrees which is perfectly normal and slowly increases in the summer to about 26-27. it then starts to drop once autum arrives and in go my cleaned or new heaters to keep a temp of around 23 -24 during the winter. ok i have to admit that my tank volume does help with stability a lot and that smaller tanks tend to have more problems with temp flactuations. so a fan, chiller or room aircon is quite often the only solution in keeping temp down.
