I have a couple of issues with the A/C over the tank.
1. I put a gutter underneath the wall unit to catch any condensation or coolant leaks that might occur. Unfortunately, the physical unit sticks out from the wall an inch or two further than my gutter does. There is a flap in the middle of the air discharge on the unit which allows you to direct the air flow up or down. This flap collects a fair amount of condensation on it from the temperature differences and then drips past the gutter, into the tank. I've actually come up with a fairly simple fix, I just have to do it. I am going to attach a piece of thin plexi to the gutter at an angle and that should direct any drips down into the gutter from now on. It wont be pretty but it should work.
2. Cleaning the unit! Because it is sitting over the tank, it is extremely difficult to reach. I almost have to get into the tank to even touch it. I haven't tried to pull off the casing yet to clean the insides but I REALLY need to. I'm really afraid of what will fall in the tank. I'm sure that the filter is disgusting and I know there is a little mildew as well. In addition, because of where my light rack is located and the fact that it only rolls in one direction, it also gets in the way of reaching the unit. I wish I had designed it to roll off the tank parallel to the tank as well as perpendicular to the tank. That would have given me more options to access the far corners of the tank and AC.
To connect the AC3 Pro to the "Internet" don't I have to connect it to a computer that stays on all the time? Right now, I don't have a computer hooked up to the router. Its just a wireless router that I use to connect my laptop to. I do want to run the wire anyway because otherwise, I have to open the door to the fish room and plug an ethernet cable into the AC3 Pro every time I want to poll its data. At least with it connected to the router permanently, I would be able to poll it whenever I was on the wireless network.
There's another issue I haven't mentioned.

I'm thinking about moving! I LOVE my house but it is only a two bedroom, one bath. I am engaged and we will be getting married next April. The house is already small and kids are only going to make it worse. So we are considering going ahead and taking advantage of this market and interest rates to find something a little bigger. At that point, I just don't know what I'm going to do about this tank. I would love to move it but I refuse to do so if I cant set it up in wall again with another fish only room with a drain in the floor. I'm spoiled now.
