SORRY ALRHA, DIDN'T READ THIS UNTIL NOW. I CAN'T PUT ANY SPS IN MY TANK UNTIL I FIGURE OUT WHATS WRONG. ALL MY MONTIS BLEACHED AND MY BLUE TORTS ARE SUFFERING AS WELL. I ALSO HAVE A POWDER BLUE STAG THATS TURNING YELLOW. THE REST OF MY SPS LOOK FINE. I'M GONNA PUT A THREAD TO SEE IF ANYONE CAN HELP. THANKS ANYWAY.
