Let me say before someone even suggests it. I have no link in any way, shape, or form to Julian Sprung, his company, or product other than being a consumer like you. I mentioned this one in particular by brand simply because it is the one I used. I suspect any good phosphate removing media would give the same results.
Also, I had different results as far as the caulerpa goes. Mine pulled a complete stop in growth. I can tell my phosban needs replacing because my refugium just started to take off again.
