Hi every one I have a question I´m about to upgrade my tank for my aro I get my tank in a week so I was thinking of putting sand for substrate, but was thinking of putting sea sand and some one told me that it might change some parameters of ph and might cause my aro not to grow, does anyone know how I can stop the ph from changing, or if I defenetly should´t use this sand, I get it cheap thats why I whanted to use it
