Printing parts for a marine fish aquarium


I want to print a part for my marine fish tank. The tank water is salty and contains delicate fish and coral.
I read online that I should use ABS or PETG.
When I look at the characteristics of Z-GLASS, it states PETG based filament with an addition of fibre glass…’
do you think this will be safe, or should I use another type of filament?


Maybe try asa filament
