First off Very Nice Hans Overall I think.....
I have a question on the Design of the Racks:
I see your using small pieces of 2 x 4 with a couple of screws to hold up the actual shelving
for the tanks. Do you find this Structurally able ?? Tremendous amount of weight once
all the tanks are on it. I've seen a few people going this route but that would be my most concern in this situation. Suggestion if I may: How about where the main posts are,
slapping up an additional piece of 2 x 4 and each shelving rests on that. Therefore the weight is transferred down to the ground. ( I have pictures indicating this procedure since I probley didn't really explain good LOL!! ) Just my 1.5 cents !!
