Hello in my 40 gallon reef tank I’ve had a New York Knicks torch for over 8 months and it started receding. At first I thought it was flat worms so I’ve dipped it once a week in red seas reef dip for the past 3 weeks and no flatworms were spotted. My ca is 420 mg is 1250 and Alk is 7.5-8. Par in its original location was around 175 and last weekend moved it down in the tank and is sitting around 110 par with slightly less flow. Below is a pic is now vs a week after I bought it.
