Since you see algae form rapidly, I'd say a water change would be a good idea. You could clean the glass before the water change. Are those nerites you have there? Good choice, mine helps with tough parts like glass corners, glass to gravel corners etc.
You could also consider adding floating plants or hornwort (ceratophyllum demersum) as they'll absorb the extra nutrients that the fresh soil leeches. Once you see the floating plants weaken, you'll know you won't be needing them any more. I believe their development to be an indicator of excess nutrients in the water column, meaning that there are more nutriens than other plants can absorb. Therefore I think they are a good choice to prevent algae (to some extend) and they are no commitment if you don't like them.
