More HOG fun with this HOG1 or 1x in saltwater. There is an unknown white spot in the middle; probably is a growth ring with brand new Green Grabber beach rocky surface below it. This scrubber will need to be brushed in the sink, because this growth is not long and strong enough to be pulled out by hand.
The growth is light yellowish green, especially in the middle, meaning strong illumination compared to nutrients in the water. After cleaning, the white surfaces will reflect more light, and the growth might be even more light colored, so they might need to be reduced by two hours a day. Or you could feed more.
