We forget how important the old adage : "The solution to pollution is dilution " often is. I have been fighting high phosphates for some time now , and even though i don't overfeed and also ensure that frozen foods are rinsed . I have noticed a recent decline in some of the corals and decided to embark on some daily water changes for a week. This has made a huge difference to th Redox and also the appearance of the corals. This has awakened a new vigor in my keep and also me. Regular water changes it will be from now on. ;-)
