Seems to reduce the noise somewhat. Heard from some people I should leave my fan on 24-7 if I want a significant drop in temperatures...Oh, BTW, the airstone comes on at the same time the fan comes on (ie. when I go to sleep). Anything else I can do? I'm a doofus when it comes to wiring so I'm not sure how to even step down the electrical energy to the fan... any other practical suggestions?  |
Wiring up your own cooling fan is dead easy. It's a matter of whether you want to do it or if you don't mind buying expensive ready-made aquarium fans. It took me less than 10 mins to do wire up my own cooling fan using a 12v adapter and a computer fan. You can add as many fans as you want/ need to the one adapter as long as the total amps is lower than the max indicated on the adapter.
Alternatively, you can use the power supply from a computer (approx RM35) and wire up the fans to that. That is what I used before Dom showed me how he did his with a 12v adapter. The adapter is less than RM15 and the computer fans cost around RM5 each.
You may already have a 12 amp adapter left over from a blown modem at home. The modem may be blown but there is a good chance the adapter is still working. That would make it even cheaper since you wouldn't have to buy one.
I don't have a digital camera at the moment but when I can, I'll take some pics and post the process in the forum. The price of cooling fans is outrageous when you consider the cost of the materials involved. Mmmm, maybe I should make some to sell..........
Incidentally, you don't need to use an airstone at night if you have regular filtration already in the tank. The airstone only adds unnecessary oxygen to your water and causes oxidation and in the longer term, algae. The oxygen produced by plants in the light hours should be more than enough to sustain the fish and plants overnight when the tank is dark.
