Welcome to the site!! This is a great place to start.
The cycle is handled by the filter, so as long as you don't change the filter, you should not see any problems with re-cycling. The lighting is really the only concern with the live plants. With that size tank, you can basically go with the 1.5-2 watts per gallon (WPG
) rule, but that's not a concrete thing. If you want to go with higher-light plants, you can go above 2 WPG
, but you will want to get into CO2
injection (much more high-tech). The lower-light option is simple, relatively inexpensive, and you can still find a pretty good selection of plants that will grow quite nicely. I'm sure there will be plenty of other people with many suggesitons. Remember to take pictures! We love to see them here, and you will enjoy looking back at the progress as time goes by.
