I have a planted aquarium and I want to improve the quality of water in my tank. I do water changes weekly (about 30-40%). I clean my filter wool regularly. Maybe not enough but I do it often. I cover the glass during day light hours.
There are 2 issues I want to solve.
1. How can I reduce algae in my tank. I get a lot.
2. How can I improve the water. Event after a clean it's still only 80-90% clean and after a couple of days it's not that great again. By the following weekend it's almost overdue for a clean.
What can I do?
