Person says can built and hold up to 1500l no problem

Picture is for 1100l. Person claims no issue on structural intergrity.... any opinions?

Are you sure that's PVC? Usually large crates/tubs like that are HDPE. In any case i wouldn't have any qualms about filling either with water. You might want to design some kind of a lid though depending on what fish you intend to keep.

The guy claim is pvc... so you think these are sturdy enough?
 
Personally the only time i'd worry about plastic tubs like that is if you were planning on keeping it outside, especially if your winters were really really cold. Plastics become more brittle the colder it gets. If you are using it inside
I wouldn't worry about it. Incidentally, somewhere on that crate should be a reference to the polymer it's manufactured from. My guess is HDPE.

i will be keeping it outside. but my country has no winter... it is sunny all round with temperatures up to 34-35 degree celsius or 93 farenheit

i did some reading and the recycle should be 2 or 5 for it to be food / aquarium safe
 
Lucky you not having winters, you should be fine then. The recycled numbers you refer to are 2 which is HDPE and 5 which is Polypropylene and yes both of these polymers are safe for your use. The only slight concern i'd have if you live in a very hot country is the long term effect that the suns UV rays may have on the polymer. UV rays, over many years, can make plastic degrade and become brittle. Plastics that are meant for outside use are usually UV stabilised. If the manufacturers made these with a view to inside use then i doubt very much they are UV stabilised.

In any case it would probably take many many hot summers of the sun beating down on your tub for it to begin to degrade. That said though if you are sinking your tub in the ground then that would be the ideal solution.

i can't sink my tub in the ground.. it would be placed at my car porch... but thanks for your explanation.. i think i will stick to glass tank or fibreglass tub then.... cheers and have a great new year

my only worry is if the i rear freshwater stingrays, not sure if they can withstand the heat. the tub will be outside but under shelter
 
You could still have it free standing above ground, just build some kind of a wooden framework around it. It would look nicer that way than just having an ugly plastic tub sat outside.
