Underwater phone housing - for an aquarium!

[Sway]

Have a marine aquarium, and really struggle to take decent pics of corals/critters through 15mm glass - especially when 'at an angle'.

So, thinking of a properly waterproof housing for my Samsung s23 ultra.

Any tips? I see a massive range, from a few hundred quid down to £30-40. Like the idea of a Bluetooth shutter trigger - and perfect world would allow me to have an orange filter permanently installed as the colour temperature of the lights is very cold.

Is there such a thing as a self adhesive filter gel?

Here's the tank, at the bluest time of day as the lights ramp down with orange filter really showing off the coral flourescence:

IP68 rating on the S23 Ultra?

1.5m for 30 mins under water, isn't that enough?

Probably, but then no filter - and it's saltwater (plus I REALLY don't want anything on/from the phone getting into my water and killing my corals!).
