In the week in between the water change, add Colombo AquaCare. Colombo Aqua Care keeps your aquarium clean and clear in a natural way. The decomposition of nutrients such as nitrates and phosphates is stimulated in a biological way. Meanwhile the water quality is stabilized and improved. Aqua Care will only give best results when used every fortnight in between the water changes. Test the water every month and correct if needed.
