Changed bulb, hair algae

[SeaHorse_Fanatic]

I can see that if there was a buildup of nutrients before & then new bulbs were added, that could fuel the hair algae outbreak.

I have Phoenix on my tanks with no hair algae, even though they are heavily stocked and well fed.

Check the status of your RO/DI unit. Water quality results in algae, not the changing types of lighting IME.

Water quality is still testing at 0 ppm. As I said before, my tank had no algae whatsoever until the bulb was switched out. The only thing I did in that time was add a couple small frags.
