Will these rocks work fine in my aquarium?
I decided to go shopping at some stone shops instead of aquarium stores for scaping rocks and I came across a few rocks for .15-.25c/pound and I'm curious as to whether or not they can be used.
My Texas tap is pretty hard so I'm a bit hesitant. tds ~250 gh/kh ~5-6.
River Stone - I'm guessing it will mostly be okay but it isn't too pretty.
Texas Holey Rock - looks okay
Lime Stone - My favorite in terms of look, but has alot of calcium.
I mostly keep/breed different strains of neo's so nothing too sensitive.
