Algae help

[Newbie2019]

Recently my tank crashed due to adding concentrated liquid food...

I'm now having a massive problem with algae.
I will do a water change and renew my phosphate remover.

Should I do anything else?
Sea hare? Fluconazole? Manually remove the algae? Peroxide? Help!

Could you post some photos of your entire tank and system?

And what are your water parameters? Nitrate? Phosphate? pH? Salinity? Alkalinity?

Are there any fish in the tank and what is your feeding schedule and history?

How long has your tank been up and how did you cycle it?

Lots of people here to help out, but need more information to understand your issues...
