My lighting hasn't changed in 7 years 3 175 m/h 10,000 k 2 vho I have a wave maker,I do water chages every two weeks, Kh 300, ph 8.5 1.021 and my temp 76. I have frag this pipe organ multipal times and the frags are doing great. I feed Dts 2 wekly and the other supliments one weekly. This piece is about a 1 1/2 year old and is about the size of a basketball. I see no sign of brown jelly, and the polyps are not dead. They just will not open. Mybe a lugal wash will do them good who knows. Back to the drawing board I guess.
