ok well there price to worry about and my school dosn't really like to spend a lot of money, 10g with 10g fuge is getting a little out of hand because its a small room and already filled with other tanks of fresh water thing and shells and skeletons and all that fun stuff, I assume the reef tank will be on his desk, I have found a way to keep water in the tank, just get a super tight fitting hood, im going to make one out of clear acrylic, if theres no room for air transfer then theres definitly not going to be water transfer, il start him off with 2 gallons of distilled water for his top off and if it really is losing water Il build a actual topper offer, lol, the fuge il be 1/3 of the whole tank, and im charging $55 for this, I hide some costs in the supplies, like stuff I already have but still will chage them for, some plumbing I have, the weld-on, the silicone, the acrylic, the tank, this puts an extra 50 bucks in my pocket so im happy
oh and yea it is a good idea for the nano cube but this would require making a fuge which will up the price and im pretty sure it only has 24w for the 12g and to me that is not enough, I like stonies and I no he wants to put everything in it
