Water parameters? Specifically interested in nitrate levels.
Looks like you have a tank full of nutrients, light, and CO2, but very little plant life to benefit from it all. Know who else likes that stuff? Algae and bacteria! Eventually the bloom will starve, but you can speed it up by throwing in some fast growing stems (hornwort is great) and floating plants. All of this is assuming your tank is done cycling and contains an abundance of nitrates.
