I was thinking about changing from gravel to sand in my tank but I am a little concerned with the release of toxic bubbles from the sand. I hear that toxic patches can form in the sand and get released and then the p's would die. Am I just overworrying?
Id say do the sand and Clean it the Twitcho Style.
I wouldnt Worry about no Toxic Patches or that Crap.
Just try and mix the sand up everyone in a while so it doesnT get stale and
form like tight Locking. Keep it Loose, Expecially if you plan on doing plants
