What's growing on my rocks?

Worried that this could be a pest. 4 month old tank.

please tank another picture with the blue channels of your light turned way down or off..
Proper color rendition is important for identification pictures and all that blue makes id pictures difficult and any times cause focus problems too..

I don't see a link in your recent post.. Its likely part of the "spam protection" features of this site.. New users/external links isn't allowed and will be blocked until moderator approved..
Your first blue image came in.. Just do that attachment procedure vs external link..

Hopefully this works

The fuzzy looking stuff on the rocks, easiest to see on top right corner of rocks.

It looks like a combination of sponges and Hydrozoans IMO.

UnderCoverDork · 04/17/2018, 06:41 PM

what kind of flow do you have in the tank?

Reefing519 · 04/17/2018, 09:17 PM

Flow was pretty sub par for a while. Still not great but there's some, have a maxijet 1200 pro running utility/jet mode in a 20 gallon. But there isn't corals in the tank so it's not a huge deal for now and I will believe upgrading soon.

yep..

and what a difference in the pictures...
Clear proof why excessive blue lighting in ID shots should be avoided..

Reefing519 · 04/18/2018, 12:15 PM

Sorry I'll know for next time to keep the lighting in check. I know sponges are nothing to worry about but what about hydrozoans?

They are fine really..
If any of it bothers you a toothbrush and some manual removal should make short work of it..

I have some similar, they come and go, snails and urchin break them off... harmless.
