GTR73 Posted February 17, 2005 Share Posted February 17, 2005 I've found a lot of good info from http://www.netmax.tk/ and it answers most aquaria questions for me: optimum growth: 25-30C growth decreases by 50% @ 17.7C growth decreased by 75% @ 7-10C no activity at 4C death at 0C or 49C nitrobacter (makes nitrates) is less tolerant of low temperatures cheers.
