Hydroid?

[amaxt]

My tank is still maturing and i started seeing these on the glass, the only place i’ve seen them is on the glass and swimming around. they’re growing in numbers and i’m worried for my tank.
i took a picture of one under a microscope too, sorry for the bad quality

Any corals or fish in your tank?

Nothing wrong with them. They bloom on a peak in one of you water parameters. This also means they will die again soon.

Just enjoy them for as long as you can.

Short of manual removal, there's no reef-safe treatment for hydroids (assuming that's what they are). Hopefully someone else can weigh-in with their take.

They might be hydrozoas? not sure if this means anything different though

will they go away on their own?

I think we need a second (or even third) opinion on exactly what they are first.
