    Hey all,

    just now installed two 400w metal halide. One is blue and other is daylight and also have 4 of t5 lights each 56w.

    my Q: when Daylight metal halide is on the water looks yellowish why? is it ok or need change ?

    2.Is it ok if I keep all the above lights on for 8H on 600L tank ?

    3.In sump have ATS with total 110w light and refugium with 70w light So I am wondering is there will be any problem with algae growth in me Display tank.


    looool to many QS :biggrin:

    Annoying just said something I never thought about: It is OK to have lower than 10000k globes in your sump because you do not care about algae growing in the sump. Well I think that is brilliant-the algae has to grow somewhere if we want to have our systems as close to nature as possible. Whats wrong with the sump":?
