A couple of photo updates. The Halimedia is growing well and the Botryocladia is seeming to color back up. It is perhaps getting used to the high lighting, because I have not reduced it at all.
The seagrasses are starting to grow and sprout new shoots. The turtle grass is faring much better than the shoal at the moment. I am thinking this is because of cyano and micro algae build up on the leaves. I have added more water flow to try and combat this.
