Just curious if anyone else uses major amounts of chaeto/ macro algae and mangroves on their SPS system and if there is any impact on colors hypothetically due to trace metals being sucked up by the fuge. I have for the first time in many years a hard time getting greens (sps) especially to be vibrant and metallic. I am wondering if my mangroves/chaeto might be using my water change ions like Iron before the corals can absorb some.
