12000g flow rate?

Don't get me wrong, I hope you are right and you don't need to supply additional heat to the water.

In regards to controlling humidity levels, those units sound more like air exchangers than dehumidifiers. If you are talking about dehumidifiers, you'll probably need something designed for an indoor pool. A dehumidifier unit large enough to handle an indoor pool will draw more than 200 watts.

The air exchangers are basically just fans that draw air out from and into a space (that's why they only draw 50 watts each because it's basically just two fans). They can lower humidity if the air being pulled in has lower RH than the air being pushed out. The issue is that the return air is typically colder (I would imagine much colder in Sweden), so you will have to make up for that lost heat.

In the winter time, if I don't open a window the room gets muggy to the point it isn't comfortable to be in there. So I now keep a window cracked and even though that lets in cold air, I insulated the crap out of the tank so that heating it isn't that expensive.

Have you thought about how you will do water changes?

The fans you are talking about are at like 3-6 watts, not 50.
These are dehumidifiers but with a very low working rate but i think they will be enough, otherwise i have 2 large dehumidifiers that i will have to run but dont think so.
I will make a "drip" system i think but it wont be so drippy.
I have not made the calculations but i want to change 2 percent everyday so there will be some water but i have a well that will take care of that, i have a pump that will fill a 1000 liter tub and from there i will have a drip system

now when i looked its going to be about 1000 liters every day so that tub will be perfect, and thats the only real cost, heat the new water.
The tub will be solar heated to a big extent and will work fairly during the winter tool, during the summer i will get it to be very hot so will have to do something about that though.

Keep us posted on how that works out. 50W dehumidifiers are tiny units. If I were you, I wouldn't even bother with them since it sounds like you already have the larger units.

Looking forward to following your progress. =)

Will do, next week or the week after that i will build a 1500-2000 gallon tank in my basement so my monsters will have somwhere to be until i build the large tank and i will do a build thread on that too.
Its going to be plywood with a viewing window thats 6.5 foot long and 2 foot high. so not that much o a viewing tank, more of a storage tank till i get my dream tank built =)
