Cooling the tank?

[Peakone]

I am radio-tv electrician so installing 'em correct should not be a problem.
I will have some pics if i have an assistant, because once i start i dont like to interupt my work.

Still thinking how to construct the waterfall, because the one i use now cant be used due to the separation between land and water... it takes a lot of space and the water side will get overwrought... but thats out of the topic

How are you going to power the fan? Are you having a tank built or are you building your own tank? I was thinking about getting some materials together to build my own. I'm curious as to how how you will wire up the fans and lights and what material you'll be using to create the gable roof style top.

I ordered the tank to be made by my desires. We have very good local builder who works rly cheap (the tank i mentioned will cost me 10euros).

About the materials for the lid ill probably use laminate and then furniture foil over it in the colors that will fit the rest of the room. For powering a fluorescent lamp you need inductors and some other stuffs which name i dont know in english When you go to the store just say you want everything to make fluorescent lamp.

For the fans its much easier. You just need an adapter, fan/s, wire and isolating tape.

You cut the bush of the adapter. Then you must find the + and the - of the wires. Usually the wires have a white bar and that mark is most of the times on the minus, but not always. If you have multimeter its easy, but if you dont you'll need a LED from old lighter for example.

You must connect the wires to the "legs" of the LED (the longer "leg" is Plus) and if it lights up you have the adapter's plus connected to the longer "leg" (the LED will most likely burn in the process :P ). Barbaric way, but it will help you find the answer

Then you just connect the + and - of the adapter to the + and - of the fan, isolate and you're done.
