Anthony I am curious as to best way to set up refugium with chaeto. Setup will be 100g rubbermaid refugium lit by 400w 6500. It will gravity feed into two prop tank. Refugium has 5" southdown bed. I want as much chaeto growth as possible. With good flow and strong lighting are there other limiting factors other than organic sources? Is iron or anything else a limiting factor? Would you dose iron or anything else or will water changes be enough?
Glad to have you on the board, just finished your book.
Andy
