It's a 5.5 gallon, but that's ok, the title is confusing lol.
The project is seeing if Co2 and fertilizers and light really do help in growing plants. I have 8 mason jars, one stem per jar, 4 getting Co2, some getting no light, some getting fertilizers and some all elements combined. I'm going to measure them to get accurate results. I'm using anacharis because it's a really fast growing plant. What was the project that your child did?
Oops, sorry I just went by the thread title. Tank looks good either way though!
I actually found pics...this was actually elementary school so rather simple: does light effect aquarium plant growth. I really miss that house, had around 15 tanks running in what was supposed to be the dining room
