Pics are fuzzy but may be tube worms or spinoid

Pic Very fuzzy but look like nudibranchs. Clearer pics can determine if good ones like berghia or bad such as monti eaters

This is what we all see below
" if in doubt - pull them out " You don't want eggs in your overflows and sump if not good ones.

I'll try pulling one out and burrow my son's microscope and see if I can get a better view, doors look like them yet looks like it's hairy but that could be the algae I'm battling now only coral in the tank is a Duncan frag
Tank is just now about 6 mo old with, 2 clowns, one spot foxface, blonde naso and a goby

Send pic of tank with algae also.
Microscope image may not help but place in a shallow bowl and take pic

It is GHA and yes typically you pull what you can by hand, reduce white light intensity and add cleaner snails such as:
astrea-cerith-turbo grazer, nassarius and nerite as well as a pencil urchin.
Are you using RODI water or tap from the faucet?
Is tank at or near a window?

Rodi, in basement but the right side of tank has a window about 12 feet away, north facing window so not much light coming in at all parameters all looking good with nitrite/nitrate at 0
Salinity is little high and working on bringing it down slowly, would like it to be 33 instead of the 34 it's at now
