This past month, the students and I have been crunching numbers concerning percentages and ratios of water changes. I (personally) have been tinkering with the plumbing of the system to get used to drilling and sealing holes so there are no leaks. I am thinking of scrapping the vertical towers just because the lighting will be extremely tricky and the set up will be very top heavy. I want the system to be in the hallway so the entire school can get excited about the project. We are a K-8 school and I think the kids will love it.
