Mushrooms reaching to the sky

Figured white only was better for them to grow aka simulate Sun I suppose...?

Time to upgrade lights I suppose

Corals need all sorts of crazy spectrum because of different chlorophyll within them. White lights are more oriented toward growth while blue spectrum (along with UV, green, red, etc.) plays important role in producing the colour. Hence reef lights will either be full spectrum or a ratio of blue and white LED mix. Since you have two separate channels (blue and white), you can use timers to simulate change in lights over the day. An example would be, start with blue for like 2 hours, turn blue and white for 4 hours, turn off blue and keep white for an hour or so and white to blue only for rest of the day (sunrise/sunset effect). I don't have any proof that its is of any help but corals do love the change.

Light upgrade is always fun. Been there done that

I leave my blues on at 100% for at least 2 or 3 hours longer than my whites.

BTW, I NEVER have just the whites on and they're only at about 30%. Your mushrooms and Zoas were definitely NOT getting enough light or were missing the blue spectrum.

Consider changing your lighting schedule around to have blues on say 11 hours and whites on 8 hours, rather than just whites on most of the time.

Not enough of the right light.....

As light penetrates water different parts of the spectrum are removed the further down it travels. In the ocean, by the time sunlight hits corals a lot of the warmer spectrum is gone and it's being hit with a much higher percentage of the blue spectrum. Blue travels the furthest through water, warmer colors like red/orange/yellow are stripped first.

So ya, turn on those blues all the time.

So odd! Mushrooms are still reaching but not as much now that blue light is on as well.
I mean these other corals are happy...aren't they?





By the way, that is a bubble you see on the hammer coral. A BIG puffy one! Looks like it's blowing a bubble gum. A good thing from what I understand. About to get a new head....?

[Coasting]

Both those corals look happy. But don't see what bubble you're talking about. Hammers usually grow new heads from the side of their skeleton.

[Jus_sum_guy]

That bubble. Right in the middle.

Anyway I am thinking if upgrading to a Kessil A350 with a gooseneck. I know it's overkill for my little nano but I can adjust the intensity and it would be useful if I got a bigger tank later on.
This would require topless tank though. What to use to stop fish from jumping? Will mesh hold them in?
