Good Day -
I am new and setting up a 110 Tank - I purchased it from a moving military member.... I only have rocks and a few hitchhikers
that came along with the tank (4 hermits and a Snail)

While waiting on the tank to cycle up so I can add fish... I have noticed 4 of these things appear... One is quite large - Are they good or bad ? If bad.. best ideas to get them out ? Thank you

Looks like some sort of Algea. My guess are phosphates are high. I am also guessing the nitrates are still high because of the initial cycle.

Do you know what all the tank parameters are?

I'm no expert, & its a little hard to tell from your photo, but possible sea sponge

Harmless sponges.
