Hmm if you’re gonna do a restart then there’s no harm with getting rid of everything and bleaching the hardscape and tank
Doesn’t mean that the algae won’t come back after you restart though, go heavy with your plants and lower your lights especially in the first weeks of your restart
If you’re thinking of keeping the stuff as it is, I would personally do a blackout for a few days
Just throw everything away and desinfect the tank with bleach solution. You can also do a bleach dipping for plants, but i wouldnt risk it. Now the tricky part is the filter. When i was restarting the tank due to chladophora, i bleached the filter media, it slowed down the cycling process but its all good now. So better to buy a new filter media. There is still a risk of contamination from using the same filter.
I blacked out my tank for a whole month. That seemed to take care of it. I left all the plants, which were all hardy (willow hygro, crypt wendtii, Java fern, Java moss). The hygro looked extremely weak and thin after a month of darkness, but it bounced back after it started to get 8-10hrs of light. The rest of them didn’t seem to be affected much by the blackout.
For best results, remove as much of it as you can prior to the blackout. This will reduce its chances of bouncing back, as well as reduce the amount of dead material that might cause ammonia to spike.

It removed Cladophora completely from my 60 l tank after a few weeks. It was the only thing that I found that ever worked on this pest.
However, it might be easier to strip down the tank, clean everything and start fresh. This way you can be sure that it is gone for good.

Mystery snail? I love them. Make sure to offer a varied diet while they’re cleaning up though 🥰
More floating plants & less bioload.
Im having the same issue. Cut back lighting, feeding, and my tank is heavily planted. This stringy algae will not fuck off.
Another option – get some Florida Flagfish. They will aggressively consume just about any thread algae in existence.

[Potassium permanganate](https://amzn.to/3Vcf13v) is what you are looking for – it’s not very common imo but it’s cheap and safer than bleach.
Potassium permanganate. Kill all the algae and snails with proper continuous dosing.
It’s pretty useful for removing them, but it is also lethal to shrimps.
Ah, this shit. This ruined my 10g as well and is basically impossible to get rid of. I redid the tank and it’s recently started to come back again.
Good luck.
I would completely start over
I had the same problem. I just restarted the tank since its stuck on everything.
