Hey everyone, first time posting, sorry if I'm doing this wrong. So, my pond has been very green ever since I constructed it ( 2-3 weeks ago). I have set up a filtration system but its not doing the trick. Here's the picture of the filtration, I have the water pump through large box filled with sand, rocks, and aquatic plants. Throughout the weeks, water has remained unchanged, if not, maybe even greener. Any tips would be appreciated, thanks!
