5 Minute Saltwater Aquarium Guide Episode #22 - Water Changes
New reefers who perform regular water changes always have much higher success rates compared to those who neglect them. The reason being is that water changes performed with regularity (every 1-2 weeks) have a multifaceted benefit to the health of the aquarium.
The substantial benefit of removing a portion of your tank's water and replacing with new, clean saltwater is waste removal and dillution of waste inside your tank. Reduced waste means less algae growth and generally healthier tank inhabitants and appearances.
Water changes will also replenish all of the necesssary major, minor and trace elements. This helps to keep more stable water parameters with all of elements found in natural seawater in proper ratio giving corals the tools they need to display their best colors and growth.
