Sea Shells In A Freshwater Tank? | My Aquarium Club
Hello! Today I went to the beach and found quite a few of cool sea shells at a saltwater beach. I believe leaving them in boiled water for a bit should be good? Though I juts don't know how long. But my most concern is how it will affect the ph. I'd like to make an ocean-themed freshwater tank in my 10 gallon with sand as substrate.
