How to understand the volume of tank before lighting

    First up all, I apologize if the caption was confusing. Here is my doubt.<br>
    <br>
    I have understood that 3WPG (3 watts per gallon) is considered 'high' lighting and is sufficient for carpeting and all. I have a 1 cubic foot betta tank (1x1x1 ft3) which-with the help of google converter- I realized that is a 7.48 Gallon tank.<br>
    <br>
    But, I have filled to a height of 3" with substrates and around an inch above is not filled with water. I have two medium size rocks also.<br>
    Now the volume of water that can be filled is approximately 5.5 Gallons.<br>
    <br>
    Which volume is to be considered here in order to light up the Tank? <br>
    Which T5 is gonna be perfect? 24 watt considering the total volume or 15 watt considering the water volume?<br>
    <br>
    Also, If I switch to LED, what should be the wattage (or lumens or whatever)?<br>
    <br>

    DIY CO2 is used.
    I have Brazilian micro sword , Rotala Rotundifolia (Hi red and green), Alteranthera Reineckii and Ludwigia Repense which I understand, do well when appropriate light and CO2 are provided.
    I also have Bacopa Monnieri, Peacock moss and
    Monosolenium tenerum.
    The light I have is just a 4W LED (philips) with 360 lumens. It looks bright but its not sufficient, I guess. Red plants are not showing their true colors and brazilian micro sword is not spreading well.
    I am using Contro soil as substrate and plant Nutrients. I've not read the link u sent me. I ll check and be back. Thanks

    I'd definitely upgrade your lighting. I recommend the Finnex Planted Plus or the Ray 2. If that's not enough, you can add a second fixture.
