Is this okay for tanks with coral and invertebrates?

I’ve never kept marine but the principle is the same Stability is for either it states so on the bottle

How much to use in a 105L aquarium? I’m very bad at maths.

5ml for each 38 Litres, so for your 105 Litre aquarium taking gravel etc into consideration 10ml should be the correct dose, the lid is also a measure and has 5 and 10ml lines marked on it.

How long is this safe to use after opened?

According to the bottle it says expires 12 months after opening.
