    Welcome from Indonesia,

    You probably have a lot of nutrients in your rocks. Or you have a very big aquarium. Your scrubber is working well, removing a lot of nutrients, but you probably need another scrubber. Can you add another one?

    Hi SM,

    thank you for reply, i'll try to add another scrubber.
    but i still confused, could i use existing specification and divide it for 2 scrubbers or i just add another one with the same exact specification like now?

    i mean like this :

    should i divide the existing specification for 2 scrubbers, so each scrubbers would be :
    LED 4 x 3Watt RED
    and using the same airpump for both scrubbers

    or

    i need to add the same exact spec that i have now, so i'll have
    2 X 7 x 3 Watt
    and
    2 airpumps?

    thank u

    Since you have so many nutrients coming out, I would just add a second scrubber.
