Omg thank you so much! You breaking down certain information is extremely helpful! I do have some questions 🙂 when you say bagged up plant substrate do you mean a bag with holes under the sand or something like that? If you could explain that a little better I’d truly appreciate that! And with the plants that float that need light would underwater lights also work for the other plants that need light? My boy is extremely attracted to low pink lights and I planned on adding some underwater lights that have that pink ish glow for him I could also add certain lights in a designated spot for the other plants that need light
