    SURF2X and silicates

    hello santamonica I currently have surf2x and I have diatoms problems due to high silicates in my marine aquarium, surf2x helps me to lower the silicates or do I have to use some resin to eliminate phosphates and silicates? my phosphates are low 0.02ppm and my nitrates 2 ppm Thank you

    Scrubbers (algae) do not remove much of the silicates. I am surprised you have diatoms with the low N and P. Usually diatoms go away first. Maybe you have high silicates in your top-off water.


    But yes, you can use GFO to reduce silicates and phosphate. Then feed more.

    Yes, it is black gravel and so is the surf2x, I think because of the lack of nutrients, I did test for potassium 420, iodine .06, iron .0

    Test for silicates? Test from top-off water?

    It is a mineral supplement I'm testing to see if it helps growth, like you were getting in your Surf.
