Do I need to make my sideboard stronger?

Hello I’ve just a new fish tank that is 100L so I have ordered a sideboard too put it. My old tank was on the kitchen work top and was a lot smaller so I had no worry’s. However could some tell me if mine will be strong enough and if not how to make it stronger.
I was thinking if I need to either get some extra plywood or some sort of wood under the top to make it thicker to to take the weight? Or some sort of pool drill though the centre shelf in the big section on to some wood to try take some weight Here is the link to the actual side board

You would be better adding cross braces rather than laying sheet flat, look at the edges of a dining table for the kind of thing, if in doubt chat to a joiner.
Alternatively replace the top with a bit of kitchen worktop.

Though my worry would be the overall strength of the unit with it being a flat pack arrangement the joints normally aren't the strong point.
Also check with the seller what they rate the top to take weight wise as I don't reckon they had an aquarium in mind.

I wouldn't risk it. Don't forget it's about 16stone you're putting on it.
