    Hi,

    I think a few things here:

    1). You may have too much light for your tank. 40 watts of T8 (do you have reflectors?) mounted on the tank will provide a lot of light and will drive the plants to grow quickly. How is the fixture mounted? Using floating plants or cloth to diffuse light will also work. Can the fixture be raised?

    This will cause a high demand for c02 and macros/micros that must be met.

    2). Please elaborate on 'marco/micro @ 5 ml'? What brand or is it DIY? This is important to know WHAT and how much ( approx ppm) of each fert.

    3). Do you use a drop checker at all? How do you know the plants have enough c02?

    4). Plants will take some time to adapt esp with a new tank. You will have nh4 issues if cycling with fish (do you have any?) and this will help fuel algae.
