I don’t claim to be an expert and can only advise as I would do.. there’s always someone more experienced out there
With that said if your water parameters are normal then I’d just continue with weekly water changes and filter maintenance...
Nitrates and Phosphates should be monitored.
Less food, less light, regular water changes should put you in the right direction.. keep tank stock down and invest in a decent clean up crew
If the GHA becomes to much manual removal is never a bad shout!
