Help with size of the tank

[Camilo Lessa]

Hey guys. I need a help from you. I was making a reef tank with 180cm x60 cm X 80 cm wildt( 1000 litters) but it was to heavy for the apartment floor.
I talked to the enginier and He say to make a reef tank that all the system need to have maximum 500 kg per square meters( 1100 lb per 10,76 square foot).

Any suggest of size,Ll be better if i put The sump on the side of the aquarium?

Regards

Well my quick maths tell me that tank has a footprint of 1,44 sq meters. So without consideration of a sump below, thats about 700l of tankvolume/ square meter. Im not at all certain about density of an average reef environment but id say since water is 1kg/l saltwater and all of the rock would have at least 1.3kg/l but thats a rough estimation that might be off. So at the moment that tank would be something like 900kg/sq meter. So im not sure if thats realistic but to lower the weight/sq meter to about a half you would have to make the tank half the height. If you still want to make it a 1000l tank you will have to double the size if the bottom. An example size that could work imo would be smthn like 180 x30x160 or smthn like 225x30x120 would propably more realistic.

Idk if this helps...
