White things on glass?

[jdwmba88]

I don't know what you'll be able to determine from these pictures, but I've got lots of white dots on my glass - especially the back. And some of them look like they're getting bigger. It's a 30G that I started about 5 months ago with dry rock and live sand.

Do they crawl?

Could be cope pods but I remember once for some reason my tank had an out break of these sponges that would grow

Do they crawl?

No, they don't appear to be moving

Hard to tell from the pics. Look up spirorbid worms and see if that matches.

They appear to be spirorbid worms. Harmless but annoying.

Are they hard?

the small white spots are hard but the bigger thing is soft

The bigger thing is a pineapple sponge. The small things are the worms as stated above. Both are harmless. The back chambers of my aio is covered with them. Only bad thing is I don’t like looking at them and I have ocd lol

You should be able to knock them off with the rough side of a sponge if you don’t like looking at them

are they beneficial at all? Are they a sign of good water quality?

Sign of good water. They are filter feeders so they take bad stuff out of the water

do you dose phyto or anything? I started dosing phyto to feed copepods and these multiplied like crazy
