Re: 4 Foot Vivarium Build From The Ground Up
I understand the displacement part 100%, as for the bulkhead location, that I didn't know.
I understand the difference between a closed loop pump and a sump being gravity fed, but I'm just pointing out ways to get around accidents, both over flowing of water and lack there of for a canister. Depending on how much misting you have and ventilation, you may have an issue where there is more water going into the Viv than is being pulled out due to evap and exchange of internal Viv air which should have high humidity and external Viv air which should be lower. Just something to consider.
In big projects like these, especially with as much work as you're putting into it, I'd hate to see you have to tear out the substrate and re drill for bulk heads.
