    Angry now what's going on!

    Bubbles!
    For the last couple of days i've been noticing more and more bubbles on the sand bed and all other surfaces. I have a Remora Pro running after it had been shut down for a couple of days so I thought it might have been the reason for the bubbles.

    Skimmer has been off all day and everything is covered again. sand bed also has brown algae starting to grow and I assume this has something to do with the bubbles being formed.

    I've upgraded from 110w pc to 220w VHO and 110w T5HO about two weeks ago, but thats the only equipment change. I did however, add a bubble coral about a week ago :blush: how ironic is that?

    A couple of pics to help out. I've done a bit of searching so far but would appreciate any help.

    are u assimuing the are bad bubbles?

    they look like they're stuck on some kind of slime.. what is that?

    i have a few theories, see if any of them make any sense to you...

    1) respiration from burrowing animals attached to some kind of casted off body slime or skin

    2) sulphur or methane gases from anaerobic processes, attached to proteins to form slimmy stuff

    3) photosynthesis from brown algae, attached to some form of slime...

    feel free to shoot these down guys.. lol

    the way i do things.. unless its hurting something, i leave it alone

    Ricepicker...I was leaning towards your #3 scenario, just hoping the "slime" isn't cyano!
    Not sure if it's bad or not....not overly worried yet, but........

    I think its in part to the change in lighting. Its algae and it will go away.

    changing in light spectrum will induce algal blooms... as logn as it doesn't cover everything (ie: suffocate corals) you're ok, cause they eventually die out

    I'd say it is #3 as well. The upgrade has caused a spike in algea and or cyano and or diatoms. It is possible that the new salt MAY contain slightly more silicate or something.
    I'd add carbon and/or phosphate removers (which also remove silicates) and take a serious look at your skimmer and r.o. unit.
    With any upgrade in lighting comes algea. There is a very basic relationship between light and algea- the more of one, the more of the other. All you can do now is try to better control nutrients.
