Chaeto

[cucumber]

Does Chaeto have small clusters of grape-like growths or did I inherit another algea with the Chaeto.

Looks like you scored some Caulerpa.

VERY good macroalgae.

I have read that Caulerpa can release nutrients back into the water. If that is the case, should I remove it?

It CAN, it doesnt always. You can prevent it from doing this by lighting the Caulerpa 24 hours a day. Both are good macros, diversity is best.

You may end up wishing you only had the chaeto. Caulerpa is very invasive. If it gets into your display, you will have a very difficult time removing it from your rocks and sand. Also, as you mentioned, caulerpa can go sexual and cause a tank crash.

Unless you really want the caulerpa and know the risks associated with it, I would recommend you stick with chaeto and remove the caulerpa.
