That's what I use in my tank, it should work fine for you. I also changed to it after my IM pack was exhausted Your phosphate is okay although higher than the ideal. Mine's way higher and my tank is fine-but all tanks are different.Quick question, I have been running the GFO and the carbon provided by innovative marine that comes with the tank but it’s been a month and it seems it’s exhausted. I ordered some 5.5oz chemipure blue to replace it with. My phosphates are at 0.08. Will adding the chemipure blue have any negative consequences to my tank?
