Temporary holding tank

[NanoCat]

I need to place all my inverts, fish, corals and rock into a temporary holding tank while I switch over to an upgraded tank size. I will be going from a 18 gallon system to a 25 gallon with sump. I should only need to leave them in the holding bin for a half day at most.

Would it be safe to use a Rubbermaid roughneck bin for this?


I have seen some people on the internet use them as full time sumps so I assume as a temporary solution it could be ok.

Does anyone have any advice.
Thanks in advance.
