View Full Version : Dirty Gunk in Chaeto

09/15/2017, 12:22 AM

Did not get a response in other post. Just would like to know
what the greyish stuff in the chaeto is. I bought from lfs few days ago.

Leave it alone or remove it?

It is in a HOB refugium right now.

I don't know what the grey stuff is? Possibly die off or lack of water flow? But since it's only a few days old in your system, you might shake the ball out a little bit in a bucket of saltwater. Even using the old saltwater from your next water change would do.

HTH :bigeyes:

Looks like a bit of bacterial snot from here..

Bacterial will collect (party woot woot) in areas of low flow...
Same with detritus,etc...

I had that same stuff and lost my huge ball of chaeto that I only bought a couple of weeks earlier. The healthy green chaeto dissolved into the gray stringy mat that could easily be separated from the healthy algae.

Will try turkey baster first to remove

There are copepods in it so trying not to disturb it
Rip it apart

no go with turkey baster

pulled off and threw away most of it, don't see any copepods moving any more

so healthy chaeto is always bright or dark green, no dirty or nasty gunk?

I don't have pods (that I know of) so when changing water I always rinse chaeto in that water. It's like rinsing a filter, always have a bunch of crap coming out of it.
My chaeto is much lighter near the lamp, overexposure to light or heat.

I am using a finnex hob refugium. after one week, my tank water is crystal clear again.
green algae on glass is diminishing. I'm seeing brown algae on the inside walls of
the refugium.

Is this normal? The chaeto has not kicked in yet or it is slowly doing it's thing
and the brown algae on the refugium walls will also clear up?

I threw in 2 snails just to do some cleaning
