Hello everyone! thanks for taking the time to read and hopefully respond. My son has a water dragon that is outgrowing his aquarium to the point he has been trying to figure out the latch to escape! once out, he out he refuses to go back, (picture a dog fighting the bath tub). we want to build a large free standing cage. ive been looking at google pics and here on HC but must be missing the details. i love the idea of a tub/aquarium built into the base and will be looking to plumb it in with a canister filter too. (yes i also do reef aquariums so that part is easy). we did make a fogger from humidifier already. Questions: 1. what size should i be looking at building? 2. what will the lighting upgrades need to be (we have 100W UVA and a 100W UVB now) 3. the foam to make the rock walls looks awesome! Can i use any foam then do the grout method? acrylic paints ok? is epoxy required (we live in a very humid coastal area and would take forever to dry i think) 4. how much water is too much? i dont want the critter to drown! 5. going bigger like this will a heat pad be required? i have every tool known to man and more than likely multiples of them as i am a carpenter/woodworker. Im very comfortable with the build but need help with the whole reptile house thing. thank you!
