Frequently Asked Questions

Do you have a shop to visit?

What means "Regrowing"?

When a macro algae species sells well we have sometimes to take it out of the sale as it will need time to regrow again.

The time for this will vary, as some macro algae species will grow very slow, whilst other - especially various  Caulerpa marine macro algae species grow quite fast.
