Refugium Hitchhikers Help

[rahul123]

I am maintaining FOWLR tank with anemones for 2 years.

Recently, few new things are popping up in refugium. Since its new for me, just want to know what are these and if these things are normal / good / bad.

1. Hard white spots in glass
2. Spiral thing in chaeto

----- Tank Parameters -----
Salinity: 1.024
PH: 8.3
Temperature: 79
Ammonia: 0
Nitrite: 0
Nitrate: 8.2
Phosphate: 0.03
Magnesium: 1350
-----------------------------------

Also need suggestion to eliminate these if these are bad for tank.

I can't really tell anything from the pictures but since you said "spiral things":
Look-up spirorbid worms if you're not already familiar with those.

They look like spirorbid worms.

Mostly neutral/harmless filter feeders that increase in numbers when food is plentiful. Some folks don’t like them or have issues with things like skimmmers if they get a population explosion.

Yes, spiriboid worms. Harmless filter feeders. Also looks like some sponge growing in the chaeto

Thanks for reply.

Anything I can do to get rid of spirorbid worm? I can scrap the glass but it started appearing to the rocks in display tank.
I just dont want it to go out of control.

Also, any idea how to get rid of the sponge which is growing in cheaeto? Or should I leave it as it is.

If you really wanted to you could crush the tubes or cover them in coral glue. But to my knowledge there isn't many ways tested to remove them. Most people don't want to as they are completely harmless/beneficial. The sponge might remove itself after a few weeks

Wouldn't bother messing with them.
