Base / Underlayment Beneath Aquarium

[mfraembs]

My new tank is coming in a few more weeks so I am finalizing the details for my stand. My question is if this foam is suitable to be placed under the tank. The builder recommends rigid insulation and not a neoprene mat so it can be slid into place. It’s a very large tank. 9’x3’x 19” tall rimless

Below are some photos of the insulation and a few of the tank stand!

I would 100% get this signed off from the builder.
I found a suitable material by sending a link to the customer service rep helping me with my build and they approved it.
