I had no cyano, then after 3 days of vodka dosing .05ml I had an outbreak. I switched to vinegar abd for the next 2 days dosed .8ml. Cyano seemed to go away. For the next 7 days I dosed 1.6ml and all my readings hit 0 so I backed down to 1ml for 2 days then .8 for the next 5 everything still reading 0.
I figured that was my maintenance dose. So I kept at it .8 and one day I noticed my birdsnest was starting to turn more white than normal. Then I noticed that pink coral in the pic start to turn white on the top. I lowered my dose to .5ml and boom cyano everywhere. Then I kinda lost track because I stopped writing down how much I dosed but I kept at .5ml for a few days and slowly tapered off to .1 today and 0 tomorrow. I think I overdosed and that's why I had issues. Maybe I'm not quite ready for carbon dosing yet. I've seen a lot of really nice tanks with vodka dosing but now it's damage control.
I hope that all made sense, I feel like I may have rambled there for a minute.
