With an HRV you'll be fine. Even better with AC.

When I moved into my current house, halides were still the thing and I did have humidity problems in winter and I think I only had the 75g and a 72g at the time. But the halides, beautiful as they were, and the fans to keep temps regulated, literally pumped water into the air. I had to admit defeat, and put in an HRV. It literally solved the problem overnight.

Now that I know what an HRV is and what it does, I want one in whatever house I live in, tanks or not, they're just really useful.

When the 280g went online I ran 3x400W Radiums. It was a sight to behold, but, that HRV for sure earned its keep, never had a problem.

Nowadays though I run a 280g with mostly LED and some T5, and between that and the terrariums, vivariums and my other indoor jungle, there's still so much less humidity than with the halides, that I only need the HRV on pretty much the lowest setting.

With the latest cold snap, I do get some frost on the windows overnight (the main problem is the window coverings trap humidity) but when I open the blinds in the morning, the windows are defrosted and dry within half an hour.

Nowadays my humidity problems come from my 13 year old having luxurious 45 minute hot showers. The bathroom becomes Costa Rica. I don't think there's an HRV capable of fixing the root cause of this, though.

Depends on the local conditions. In southern Saskatchewan I have a humidifier pumping steam into a 12x13' bedroom and I can't get that one room above 25%. If I were having problems with the humidity I would try to get to the moisture before it entered the room. Sending it out of the house would pump heat out of the house at the same time. If you had a thick enough floating light hood, you could install a dehumidifier in it that brings in air from under the hood, and pushes the dried air out of the hood into the room. Rather than having a collection bucket to empty, it could just drip back into the aquarium. Could work.
