Excess moisture in fish room

[christyf5]

I had a small dehumidifier in my previously small fish room. Its currently in my basement with the tank and I empty it daily. Worked great for a small room. It still fills up quickly but I honestly don't think we have a huge humidity problem (although the fact that it fills up probably says differently )

Oh man dumping the water tray everyday seems like adding more choir to the already huge list from my tank.

Lol. Guess you're tied to something more permanent then. Have fun with drilling and wiring

No windows in my fish room. It's in the middle of my house.

My 220gal system is in a 7'x8' room. I'm using a 110cfm bathroom exhaust fan (draws about 1 amp) on a dehumidistat. I also have a 4" hole in the exterior wall to draw fresh (typically cool) outdoor air inside. The humidity in there usually sits around 45% with little to no impact on the rest of the house.

Dehumidifiers produce a lot of heat, require a lot of electricity (our old one drew 3 amps and couldn't keep up) and are typically much noisier than exhaust fans.

Put a palm tree and a lawn chair in there.... paradise

I still say just bash a random huge hole in the ceiling , think about it......

it fixes your issue and allows a steady swap of stale for fresh air, no need to worry about static pressure and all that fancy jazz

It costs nothing at all iin fact you'll gain a piece or tow of 2x4', small piece of drywall some insulation , screws and even a shingle or two from the demo.......that's a plus in my books.

It hasn't got to be pretty if you don't have a saw just bash a hole down with your foot it's in your fish room so doesn't need to be pretty .

Come winter temps will stay low and chiller runs less and come summer heaters will run less

Your carbon footprint will be small and more money for corals wi all the power savings

No need for mechanical failures works 24/7 flawlessly



If you create a sheet and weigh the pros vs cons you'll find this is the way to go by far , you should take my work for it I have a lot of posts so it has to be true



Really the only other better alternative is to cut two holes in your roof

Potentially yes, if you bought new and had a professional install it.
I bought mine second hand for less than a new low sone bath fan at home depot and installed it myself. But being a journeyman sheet metal worker and having installed hundreds of them, it wasn't a big deal.
It is "generally" considered the best way to fix the problem you've described. Any other method described using bath fans are just trying to imitate what an HRV does, albeit for less initial money but without re-couperating any heat you've already paid to heat by some other means. And if no make up air is provided, creating negative pressure in a home which could be dangerous.
An average of 50 Canadians die every year from carbon monoxide poisoning, not to mention the hundreds who get sick from it and are permanently disabled.
Only reason I harp on this one thing, is I'm also retired firefighter/EMT and have seen and dealt with the effects of CO poisoning more than once. It is a definite risk when installing exhaust fans and not providing make up air in homes with gas fired appliances.
This post isn't specifically directed at you, Jason604, I know often times funds and manpower are often deciding factors of what we would like to do over what we CAN do. I've seen this question asked over and over here and on RC and the $60 bath fan wins out many times over. And that's totally fine as long as you can also provide some fresh air vent that allows the rooms air pressure to balance. But it appears generally people greatly underestimate the danger of CO poisoning. I can't tell you how many homes I've been to where people have plugged up their combustion air pails by the furnace and hot water tanks with towels because they always feel cold air coming in. It just makes me shake my head. Anyway... I've said my peace, I won't say anymore.

De-humidifiers do work, but at the cost of adding heat and a much greater use of electricity.

I have an HRV 6 inch vent from my sump area in the fish room. Newer houses have the HRV installed at build. Have you checked for this?
