How do you deal with humidity from your tank?

[CastawayReef]

Hi Reefers!

I'm dealing with some humidity issues with my 120 castaway reef. My tank is in the basement and if I don't run my dehumidifier the RH can reach 71%.

The 70 pint danby dehumidifier I have runs constantly and raises room temperature a few degrees and is loud.

My question is how do you deal with humidity from your reef tank? Totally closing the tank top and sump with cover will work bit no gas exhange.

Any ideas?

Well I had a lot more tanks so I installed an HRV.

Being as I have a lot of evaporation from my tank as it gets very hot where my tank is placed you would think I would have high humidity but my tank is surrounded by plants that actually take a lot of the moisture out of the air best humidifier going IMO

HRV for the excess in winter and the AC during the warm times keeps the house cool so not relying on evap cooling and what moisture I have condenses out with the AC.

This is interesting.

After a few years you will get used to the dehumidifier hum and increased temp.

If you have forced air heating turn your fan on so it circulates the air in the house. That alone will make a significant difference in basement humidity.

I have an HRV as well with a dehumidistat in my canopy and in my fish room controlling it.

If your basement isn't finished a bathroom fan can vent out a lot of the extra moisture

I run my blower on the furnace to move air in the house. We also have an exhaust fan that I run. Recently I bought a Danby 40L / day dehumidifier and it runs in my utility room 24/7 with a drain hose to the floor drain. I'd like a larger dehumidifier, this one is a bit small but better than nothing...

This is a 5 yr house.... If we ever build, I'll put a dehumidifier in the furnace or a vent to dump humid air from the tank area outside.... This is prob the easiest...

That's what I do. We don't have a basement, but we keep the furnace fan on 24/7 for air circulation, plus it filters the air. :)

My tanks have lexan covers.

My tanks have lexan covers.

Same. No issues with light penetrating the lexan either even when I let it get covered in salt and dust and who knows what else.

Sump isn't covered but its in the stand and don't really have an issue with it sneaking out of the stand and causing issues.

Mine is a 325gal in-wall system with a 50 sqft equipment room. A 110 CFM bathroom exhaust fan blows out the hot humid air and a 4" hole in the exterior wall of the house allows fresh air to be drawn inside. Humidity doesn't exceed 45% but room temperature due to MH lighting climbs to around 30 C each day. I'm going to try a 300 CFM fan and if that doesn't work... LED lighting is in my future.

I was lucky, my house came with an HRV when I bought it. Never any humidity issues

[mark]

depending where you live, ERV also an option

I have a glass cover on my tank. My sump is open and I have a opening in my stand so no moisture builds up.
