 Re: Freshwater Refugium?
rlking having the light on 24 hours a day is fine. Scientific study show that freshwater plants grow in proportion to the amount of light per day and do not need rest period. For refugium you probably want open top setup because the fastest grower are floating plants. The amount of nutrients absorbed are in proportion to the growth of the plant. And floating plants are many multiples faster at growing than immersed plants. Duckweeds are nice but they are small. Get the sewage plants as people mentioned like water hyacinth, water lettuce etc. |
