As for the leak's, Yes plan ahead & don't run any electric where might develop a problem. And all together I have 34 Pod's running at all time's, 7-20gal. res. and have never had a major problem.

Use good material's, make good working design, and do a good job in construction!!!

Here is what inspired me to build the Pod's like I have!!
