I have recently been struggling with my euphyllia receding and dying. As a result I did an ICP which showed high levels of aluminium (137.85μg/l). My assumption is that this is from the marinepure balls in the sump. Over a week or 2 I did 3 x 20-30% changes and ran some rowaphos. This brought it down to 88.77μg/l. I was hoping for it to bring it down a bit more since I’ve heard people saying a small bag brought theirs down massively.
How efficient actually is it? And what is the easiest / best way to bring it down.
