I can’t see much GHA in your pics so I’m not thinking it’s sucking up much.So you feel fairly confident from what I’ve been able to explain that it’s not a false zero. And by adding more nutrients, I wouldn’t be doing a disservice
I do see a tuff here and there and even that seems small..
Maybe I can’t truly see the extent of the algae growth, and if there’s a lot, then sure, it may be acting like a Fuge.
The tank I see looks great, and is 6 months old.
Maybe a pic in white only may display the problem better, if that exists, if not, I stick to the steps posted.
