This is more of a lesson learned than trying something. Got some cheap gravel from the cement section of a big box store. The gravel has been in a couple tank for over year.
Learned two negatives, first some of it has metal shavings which led to some rust which is no big deal. This is how our granparents got iron in thier diet.
Two: one of the tanks had hardened rock layer along the bottom which wouldn't come up with a child's shovel.
Be warned if you try it.
They will live in a range of PH. Rain/snow melt/etc. changes the natural ph even in large bodies of water.
You can add a piece of certain woods, crushed coral, or almond leaf can help stabilize the water.
Get a small basket and some pool noodle. Glue the noddle to the basket. Place the potential parent and basket in an empty tank for a few days. The eggs should fall through the basket and away from the parents to be eaten. Make sure the tank has plenty of film growing. That's the basics of any egg spawner breeding.
