Still battling some unknown combination of hazy + green water...but did a huuge water change: 75% ...and then a 50% one after the other. Almost lost a shrimp and a tetra due to water change. But luckily they look better now.
Removed the lily pipes which are full of algae and they are soaking in bleach until I get my brush. Using the stock eheim spray bar....I actually like it very much...ofcourse apart from the looks. I love the nice effect on the water surface. Soo beautiful.
