    I use the EI now for 8 weeks and I had very good results in growth since then. Minor brush algae occuring at the beginning but now going away.
    Today my new hood arrived, equipped with 4x24W T5 tubes. Before I had 3x18W T8.
    The tank is 112l/30gal so I would now have 3.2W/gal.

    Is that maybe too much? Will I run into trouble soon? Should I reduce the lighting time? At the moment I use 5hlight / 4hoursbreak / 5hlight.
    I think about having 2 tubes only on for 2x3h, I don´t know.
    I always wanted to have a tank were poor lighting is not an issue but maybe now I overdid it.

    Has anybody any experience that he could share?

    After an hour of illumination my tank looks like a shaken soda bottle, it is pearling heavily everywhere, I almost do not see the fish...

    Do not do the 4 hours off method, bad idea..............

    Do 10 hours total and have 2 x24 watt on for 10 hours and all of them on for 3-4 hours in the middle of the day.

    Are you interested in increased pruning and growth rates or just good growth without algae?

    More light= more work.
    A spike in the middle of the day will still cause the plants to pearl well, but not drain so much from the tank and grow quite as fast etc.
