[digitalsteve]

hey guys , i am having a humidity issue with my tank , it is in my room and it seems like there is a lot of added moisture in the air. i understand that with the tank there will be a levels of evaporation that i have to cope with but it seems a little excessive. is there any way to combat this problem ? should i go with a glass top?
dehumidifier? w

what about a CaCl dehumidifier like the drymax one? how efficient are they ?

any help will be appreciated
