Everyone says for salt tanks you need a specific substrate because it will keep the pH where you want it (crushed coral etc.). But if salt water or adding marine salt into the water raises the pH anyway whats the issue? I want to use pea gravel from home depot that I'v always used on my freshwater tanks.
I learned that calcium and other things in the substrate is healthy for the tank. The gravel would not have this, I see now, but that would mean it is possible for me to gather lots of shells from the beach and put them into the tank no?
I realize this wouldnt be the most ideal setup for the majority of you guys, but it would work wouldnt it? A bunch of crushed shells ontop of some gravel?
