In the area where I live, nobody I know, who got more than one tank use any type of chemical to dechlorinate the tapp water, no need to do it here. > Are you suggesting that I just use some PH down to lower the ph and then > leave it at that? > Or just lower the PH and add blackwater extract? I would use both. I would be carefull with the pH down stuff because it might give you an algea boom and remember to lower the pH gently to avoid pH shock I have also used peat to lower the pH and found it quite efficient.
