Hello All,

I am a long time reader here but first time poster. I am in the beginning stages of setting up a 75 gallon reef tank and I need some help. To give you a bit of background, I have been out of the hobby for about 10 years, but I did have an 35 gallon reef when I was in it. It was doing well until it leaked and I lost everything.

So now, current day I am getting back into it, and I have a few questions. So far here is the equipment I have:

- 75 gallon tank
- 3 x 165w Dsuny LED Panels with Controller
- 4 large powerheads
- 100lbs 'Dead' live rock
- A few pumps
- Vertex Protein Skimmer
- 2 x 300W Heaters

Still to purchase:

- Tank for Sump
- Overflow or Drill 75 gallon tank (I haven't decided yet)

Questions:

Placement of the tank:

1. I will be placing the tank in my 3 season room at the back of my house. The room is not insulated, but it has an extension running off the HVAC into it. I live in Canada where we do have a huge change in temperature from summer to winter (85f in the summer to 10f or less in the winter). It can get below freezing in the room I want to use for this. So here is my question. In regards to keeping my heating bill as low as possible what do you think is the best solution?:

a. I think building an isolated stand where the tank is seen from the front and the back only is the best option. Everything else built into a stand with foam insulation. I would build a box to go above the tank that would hold the lights, and then on either side of the tank run foam insulation inside of the cabinets. The tank would sit on foam insulation and then the cabinet underneath would be completely insulated with foam. This is where I would keep the heaters, skimmer, etc. My thought is the heat generated from the lights would help keep the tank warm in the winter, and the cabinet being fully insulated underneath would keep it from loosing much heat. In the summer, the opposite would be true and the tank would stay cooler longer and not see huge changes.

b. Insulate the room. There is more cost to this than I would like, although I could do portions of it. The room is built on a concrete slab, and insulating the floor is not an option. Most of the room is single pane windows (3/4 sides) so I could insulate about 2.5 feet up from the floor. The entire ceiling is open and it could have insulation added to it. This will be a considerable expense and more work than I was hoping, but if it is going to save absorbent electrical costs than it make sense.

Does anybody have experience with anything similar? I know people have put tanks in their garage or in sheds in the back yard to create fish rooms, so this is fairly similar, but I'm not sure if people are doing it in climates that change so much.

Question 2:

1. Behind the room I am putting the tank I have my hot tub. It is tight against the back window of the sun room. My thought is I want to put the tank against the window. I want to set it up so that while you are in the hot tub you can view the tank very well. Where the hot tub is sitting it is mostly covered, so there isn't a huge worry of direct sunlight coming into the window, but there still will be ambient outdoor light. Also the window does get fairly cold as it is only single pane. Does anybody see an issue with this? I am thinking that I will have to adjust the lighting cycle to allow for the light from outside, but other than that it shouldn't change too much, if I can solve problem #1.

Thank you all for reading this far, I am sure I will have more questions, but I am really excited to be back in the hobby, and I think this could be a really cool setup!
 
Welcome to R2R! This does look difficult. What about putting the tank in a closet with windows to view the tank and heating the "closet" with a space heater? Could be cooled with a small A/C or a chiller in the summer.
 
Thank you!

Thats sort of what I was thinking with the stand being so big and insulated around it. If everywhere around the tank except the viewing area at the front and the back was closed off with a thick insulated stand that would work. I could run HVAC over to that as well as that wouldn't be too much work (About 15' of venting). I guess that would also provide air movement around the tank too.
 
Welcome to R2R!

The biggest problem you have are single pane windows and the uninsulated ceiling. Can you put storm windows up during the winters?

Thank you for the welcome!

For the windows I could probably do something for all the windows other than the one the tank is against. The main goal is to be able to see the tank from outside. I know it is lofty, but goals are supposed to be!
 
Sounds like a good plan on the build. Welcome to R2R!
 
Welcome to R2R! Looking forward to following along with your build.

Welcome!!
This might be your best option to build an enclosed space in the garage. Winters will put your tank heaters to some serious work so you will definitely need 2 or maybe even 3 running incase one fails (plus extras on hand just incase). Also a power source to keep them running for when you lose power. The heat in the tank will dissipate pretty quickly in a room that can get that cold.

Edit: building a insulated closet might cost more upfront, but you will spend less electricity plus you can have your sump and other "ugly" equiptment hidden and organized.

Sounds like a the closet is what you guys think is best. Would this work?

Frame out an area where the tank will be going out of 3" thick walls. Insulate the floor, ceiling and walls. Cut out the wall where the tank needs to be seen. A picture is worth a thousand words so what do you guys think of this?

with a double panel window between the tank and hot tub. It would look really good with both sides viewable! You can invite us all over AFTER its built. ;)

Im assuming the side with the fireplace is inside the house and is tempature regulated? If so, you can skip all that insulation and just worry about the glass & wall between the tank and tub.

The fireplace is in a 3 season room that is not insulated unfortunately. I ran an extension from the furnace into the room so that we get some hot air only went the furnace is on. There is a door on the other side of the room that takes you into the house and that is closed unless we are in the room. I find that if in the middle of the winter, the room will drop below freezing, but if I turn the furnace on and get a fire going I can get the room up to about 68f in about 2 hours.

The window is a single pane window, so unfortunately it doesn't provide much help at all....
 
Thank you for the welcome!

My only issue with the design you have shown is you won’t be able to see the tank from inside at all. I wonder if I was to put another piece of glass or acrylic to shield the tank from cold air? Not the same effect but some I hope. I have access to 1/4” acrylic for free so I could make a sort of double pane using the tank as a single pane and the acrylic as a second?
 
I did some calculations last night. If I was to make it as a double pane with acrylic, as long as the airflow was sealed in between the tank glass and the acrylic, it would make a huge difference as cold air wouldn't directly be hitting the tank glass.

I'm going to start this weekend and I will post some pictures for everybody! Thank you all for the input!
