Emerald algae on my hornwort, bad?

That looks like blue-green algae, Cyanobacteria. It does quite quickly all across your aquarium and is extremely hard to get out. I recommend taking that piece of hornwort out (or at least trimming that part off), and maybe looking into how to get rid of it if it does start spreading more.

Yep, cyanobacteria like Crabby said.

Get rid of it as quickly as possible.

Ok cut that spot out and another chunk that had a couple suspect areas of a greener cast. Eyes peeled for any others showing up. How have I developed Cyanobacteria? Too much BacteAE?

Probably not the BacterAE. Cyanobacteria is usually caused by a combination of low flow, excess light, and some sort of nutrient imbalance. I believe phosphate is quite tied into it (too high or too low can cause a bunch of different algaes), and of course high levels of nitrate (waste) will lead to algae outbreaks. Chances are you'll get some more showing up, so maybe drop light levels and test nitrate?

Low water flow or in other words, low oxygen levels in the water.

Does your tank have any filter outlet breaking water surface tension?

I cleared out 50% of floating plants. HAng on back filter moves surface and water below pretty well. I can cut back on light hours. Not much other algae around the tank. Just checked nitrates via sapi tested 0ppm.

      Midges are cosmopolitan.  Bloodworms are commonly of the genus Chironomus.. and fun-fact the red colour is haemoglobin which binds oxygen (as it does in our blood) allowing midge larvae to live in low oxygen environments like the sludge in the bottom of a fish-food bucket. https://www.naturespot.org.uk/species/chironomus-plumosus

      Thats most interesting, I didn't think we had midges here in SE England, but maybe just get a small number. We certainly get mosquito here though as there are 2 lakes in the grounds, I have friends coming sunday and they will be sent to get some daphnia and mosquito larvae, they usually take a tub full home for their fish as well! I will pass on the tip about the jelly if they see any in their bucket! Simon

      Bloodworms are larvae of midges (mosquito-like flies without the "pronger") The adults lay eggs in the water that look like little sacks of jelly.  You sometimes see them hanging from the water surface or stuck to the edges of the bucket.  You can wipe the "jelly" off and put it in your tank and when the larvae hatch they are great fry food.... but if you dont have enough fish to eat them they may live in the tank and emerge to fly around your house.

      I think the fins will healquite quickly if they do get damaged, it just looks a bit worrying to the owners eye! Simon

      See, that’s the kind of conciseness in a post that I completely lack 😂 Yeah I’ve also heard it can be. Luckily no damaged fins, besides a teeny tiny tear in one of Tessa’s fins.
