Mushrooms reaching to the sky

[hfp75]

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....?

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?

[Coasting]

Ah its probably just doing a hammer thing. I wouldn't worry. It still looks happy. Sometimes they expand, or contract, or poop, or whatever.

Most people use clear mesh with a window screen kit. I use Lexan or bullet proof glass lol Unless your fish weighs a good amount they wont be able to jump and knock the lid off. I ran my LEDs through the lexan. no open top. gotta keep cats and dog hair out.

[Jus_sum_guy]

Oh right! Dog hair! I have a husky that likes to shed!

You mean this?
