Ugly stage? Or something else?

[R33FDr3amer]

I have been researching and can't really figure out if this is normal or something I should be concerned with. Tank is 5 months old. I've added a small cuc (5 trochus, 1 tiger conch & a blood red fire shrimp) They cleaned it all up when I 1st added them but it has come right back. Now my snails just wanna hang out on the glass or each other lol

So, is this part of the ugly stage or something more nasty that I need to be concerned with?

Do you think I should add more cuc now or wait?

The green leafy stuff looks like bryopsis. You will have to pull it out.
Yellow is prob beginning of some other algae or diatoms.
Snails live on different things depending on the species. Get some other types.

As stated, pull what you can by hand, reduce white lighting and utilize snails such as: Trochus, nerite, astrea and margarita
