How big is the tank? On my 5.5 gallon tanks in the summer I was using a computer fan and the power cord from an old answering machine.
Dealing with the direct sunlight would be the first step and it's tough to give much good advice on that without knowing the physical layout--shades, blinds, shielding from potted plants, etc. Your next low tech line of defense is evaporation---my main tank has a chiller on it, but my riparium is cooled just as well by the water passing thru a planted HOB and trickling down a moss lined perforated ramp. If you have to have a hood or lid, small fans blowing across the surface to increase evaporation can do wonders as well.hello, i have re-introduced myself in the intro problem, if you read that thread you will know about the temperature problem.
so the tank gets too hot in the summer, and we're on a budget. mos tof what we use comes from the teachers pocket. we need a method to keep the water cool next summer, since now it's right about winter time. does anyone have any clues on how we can do this? a $500 chiller is out of the question. i ran the idea of a mini freezer with tubing going through it to cool water off, but he wants something simpler. who can help me out? please know that this information will not just help me, but it will help an entire high school.
thanks! but i'm one of the kids too haha. i'm doing this for many reasons, one of them is because our rival school in the same town has a fish tank, and i want to outdo them haha, so rivalry is a factor. don't know about the shade, but i can probably get the woods club or class to build a canopy for us :icon_mrgr :icon_mrgr :icon_mrgr the winter part isn't really a problem, it's the summer time when the weather outside gets really hot, an to make things worse the room the aquariums are in aren't really ventilated.as i said, i need as many ideas as i can. the ventilation and canopy are a few, but the more the merrier.An improvised shade to block the sun will help. Make as much room for air to circulate over the water surface as is practical. Sometimes lowering the water so that there is more space as well as more splash will help. Fans blowing humid air away from the area helps up the evaporation. Using/placing filters and any other motors so they can get more air circulation will help to keep this heat out of the tank. Turning off any equipment like lights that can be removed will help. During the winter consider setting any heaters used so they maintain the tank at a bit lower temperature at night. That will let the tank start from a lower point when the heat comes in from the sun.
Good luck and I apreciate what you are trying to do for the kids! Thanks....
You can get shade cloth from any place that sells greenhouse/indoor plant supplies (also available online) - get the woodworkers to make a nice frame to suspend the shade cloth over the tanks.don't know about the shade, but i can probably get the woods club or class to build a canopy for us :icon_mrgr :icon_mrgr :icon_mrgr the win
It is in a school. That doesn't work for Saturday and Sundays.during summer times in my previous residence, it would get warm in my place. My tank would reach 88 during the day. To help mediate this, I would use frozen 2 liter bottles. 2 bottles a day work pretty well to keep the tank in the mid 70s
That will get old really quick. I think fans on a temp controller is the best low cost, least hassle solution.i can come in saturdays and maybe sundays, i'm just not sure if the bottles will have an impact.
