I would suggest that you use plants as a filtration system in these ponds. This would make it more of a learning process, researching what plants to get, what plant you are aloowed to use in FL. also the science of natural pond filtration. Would be cheaper than buying a filtration system and less mothly maintence. I think that would be much more fulling than using a manufactored system. After all your in school to learn.
