Depends on the length but it could be retofited to fit the light. You will need to ensure this is done by one of your parents (not you
) but the electrical will also need to be rewired to incorporate a new ballast to run the PC
lighting. The one you have now will not run a PC
light. One option that I neglected to mention was if your 12w is a mogul type (screw type bulb) you can also get a PC
mugul like this >>mini compact
<<. It still won't promote the coralline growth but it will help sustain it and the existing ballast should be fine.
can i upgrade a tube later, and just not have any growth or do i need it? just wanting to get any and all suggestions i can lol
As I said above it can be upgraded later. The filtration effects of the rock are not light dependant so if the coralline is not a concern, it is not required. If/when you upgrade later, the coralline can easily be re-seeded later on.
