i ordered a couple green gobies to put in my nano tank, but here's my dilemma, the nano has been up and running since christmas and i put "live sand" who only knows how old that was? my test kit that at this point i can't trust says ammo off the chart, nitrites off the chart, ph okay, but i have asternia stars in there doing fine snails doing fine and a scarlet hermit doing fine. added live rock with mushrooms,green buttons, yellow polyps all doing fine, do i put the fish in or put them in my 65 and never be able to catch them out. :shout:
