Sounds like a good start, get a journal going, post pictures and the processes you are following. You will likely get sound advise from experienced members so you can decide on an informed routine that you then stick to.
There is plenty of wood without epiphytes attached that would benefit from a brush, same for the rocks especially at the front, you might even be able to lift them out and scrub them if they aren't buried. Old credit card on the glass pushing down to substrate and behind where wood is close to the glass.
CO2, flow and distrubution is always a work in progress as the tank changes with plant mass. If you have growth issues, algae in isolated areas and don't see everything gently moving then you need to tweak it. I'd suggest moving the drop checker to the opposite side of the tank to help understand if the flow is getting around the tank. What looks to be bba in the back needs attention but a better photo will help.
Algae in its self isn't bad but in an aquascape the idea is to minimise it. It also isn't caused by excess nutrients, its caused by inbalance of light, flow ,co2 and nutrients.
All this info is available within the articles section of the forum. Please read them and arm yourself with this info and then ask questions, IN A JOURNAL, based on what you have learnt. Happy to help but you gotta do the work first fella 😉👍
