I have a gbta over 6 months and it still ok and fully inflate with 6-8 in diameter. My nem start to have issue when I took 1 month vacation in december, I use auto-thaw feeder to feed them by a cube of reef frenzy. My uncle was the one who put a small cube of reef frenzy. When I came back, my nem only 3-4 in and haven’t fully infate until now. I know that nitrate will be really high after that month, but i brought everything to normal after a month. My kessil also have skme broken small led, so i try to check the par and it was 130. “ my nem did well in 150-170”. I try to get a new kessil and turn more light for it with 230 and it seem deflate over 2 weeks. Last couple weeks ago, i turn my light down to 150 par which is the best range for nem before. In fact, everything should be back on track as normal and my coral and other nem pretty happy, but not my gbta. I just notice its root lost color which should be pink, and keep deflate over 2 months. Please help me solve this issue
