Ok so I found about this stuff from another thread I saw on here and read up on it and it sounds like it can help me. I always have super low, almost 0 Ns and Ps and wanted to attempt to feed my corals. Now that I have it in front of me I am super nervous to use it and I am scared to screw my water chemistry up. Like I said I have almost 0 phosphate when I test on either Hanna or Nyos test kit and on the RS and Salifert Nitrate test the water is hardly pink. I do have some GHA here and there that I have been pulling by hand (finger) almost daily so obviously my tank has N&P its just the GHA is using it up. Anyone use this product? can anyone offer advice? Like all things I put into my tank I am going to start half dose and take it slow but I would like to hear what others have been doing. I have a 9 month old RSR 250 mixed reef. would this product make the GHA I do have explode in growth?
