The algae that Walker and the others brought down to Remey's lab proved not to be the last. They managed to be on the top deck when the sun was rising. It appeared that there had been a lot more lunar algae than they expected.
The sun had illuminated the waves which carried chunks of already dying lunar algae. It had been killed the moment that the sun rose and it had been overloaded with too much mana. The reason that the algae grew was the moonlight. It was gentle and not as harsh as the sun. note it was getting too much light all at once and unable to grow to compensate.
The glowing pieces of alga were turning brown and sticking together. They were more or less chunks of useless seaweed. The ships didn't need to worry about them while they moved. They could cut through them as long as they weren't too large of chunks. This was why those on lookout were guiding the steering of the fleet around the larger floating sections of lunar algae.
