An HRV is the answer guys. The heat recovery air to air exchanger, keeps the air fresh and removes the humidity.

In the summer I use a de-humidifier also, as the outside air is to humid for the HRV to do any good.

Bob, but all of your tanks are small...you have 2 nano reefs right? That's not going to make much of a difference. I've got a 180 with a 50 gal fuge and 12 gallon sump, a 150 with a 75 gallon sump, and a 54 with a 20 gallon sump...that's a lot of open water in a 600 sq ft main level.

Wayner, is yours a stand alone type? How much and how well does it work?

Also... I've hardly had my heat on in the house because the tanks heat the house in the afternoon/evening and we turn the heat on when we get home from work, and then off before we hit the sack...so I can't rely on my furnace/heat for taking the humidity out....

Any other ideas?

Thanks..

Dez/Bob.
Bob also runs glass tops on his tank so that would make a diffrence as well.

I am sorry guys, I will stand by my statement. When it gets a bit colder i do not think we have to dehumidify. I have a friend who has a hot tub, and has no problems. You will have to go a long way to equal a hot tub. :D

I need one
 

In my basement I have an open 100 ish gallon pond, a 90 gallon tank and now a 180 gallon tank. The water circulates through a big filter and falls back into the system. Above the tank I have a 1000W Mh light, and the floor has radiant heating. I am planning on adding another 500 W of lights this month. Already my windows are dripping. You can easily detect the humidty when you desend ino my basement. I add 3 gallons of water most days to the system (some is used to water plants ... which I have in abundance).

I would really like to get a plan for one and would be interested in manufacturing one. Anyone else interested? Anyone have a plan?

I dont have a plan but of course I am always intresed in making something and using my brain. :D

Doug is right. You guys will need an HRV to remove the humidity. If you have a two story house this is the only way to go. It attaches to your existing duct work so it will remove moist air from all over the house. I have one of these units in my house. Unforyunetely you will have to have somebody come down and drill 2 holes through your house walls to get fresh air in. the rest is a fairley easy install if you are somewhat mechanically inclined. Hope this helps

I have a lot of water in here..... :shock:

And, by all accounts my house should be the worst, as it is not even properly vented - (it was built with a heat exchanger which we have not had in operation for the 8years or so we have owned the house, not due to limited research......) This means no bathroom vents, kitchen vents, etc.

Have you guys got a window open??? :?

Hi, We had a stand alone model for years but I have switched to a ceiling model. No more expensive, doesn't take any room and QUIET. The floor one was noisy, it started gumming up and only working intermitently. The ceiling one is mounted in attic. (Got it from electrical friend for $120, I think it is 220cfm???) Ducting cost $20, vent to roof $10 some tar to seal with$10 and cone vent for ceiling $5. Labour was free in exchange for fish tank :lol: It took about 3 hours to install and I bought humidistat for wall ($20). Just my $.02. Rachel

I don't think we can even begin to compare to BC...my only destination where my luggage arrives wet.. :lol: 8)
