So my tank has been up and running for around six months and I've noticed I'm not growing coraline algae on the walls or my power head. The rocks are covered in it, and my coral is not only thriving but growing as well. After doing some reading I learned it could be because of high nitrates and phosphates which as luck would have it I had both. After a lot of water changes and the addition of a carbon sponge to my wet/dry the nitrates have dropped to zero however the phosphates are still around 3.0 according to my API test kit. So my question is what else can I use to lower the phosphates??
Thanks guys
