Anyone using these in their refugium? Been looking at them, cheato with live rock and sand, or crushed coral.
It depends on how large the algae colony is. Halimeda uses calcium. I wouldn't keep it because of that. If you had a massive colony of halimeda, I would imagine it would pull calcium like a coral would.
