That's good but until you find & fix the cause of cyano it will come back after antibiotic TX, sorry, that's my experience. High light, higher heat...in my cases (both coasts), those were the big problems, but also high or no nitrate can add to the problem. I've been in the "seasonal rollercoaster", it's very frustrating!
Your wisteria leaves look like they have some cyano (BGA) to me. Cut your light down to 6 hours/day & maybe build to 7 or 8. That can help with the diatoms too.
You might also try the "total blackout" method. No light from anywhere! Wrap the tank in trash bags for 3 or 4 days, no peeking/ no feeding...nothing! But...IME it's not a long term answer...
