Iodine does not remain stable for a long time in an aquarium. It is quickly converted into iodide, turning it ineffective for many plants and animals. A constant iodine level is achieved by daily addition of sera marin 7. Varying concentrations and deficiencies are avoided. sera marin 7 in the dropper bottle allows daily addition without annoying measuring. .   Sera Iodine 7  50ml   £3.99             HOME - All Food -Outdoor / Pond - Filter spare Parts - SPECIAL OFFERS - Marine Aquarium - Freshwater Aquaria - Cleaning Supplies - Goldfish Supplies - Airline  Supplies - ORNAMENTS - REPTILES
