Carbon dosing algae??

[JUSKIDN]

I’m carbon dosing with vinegar using 20ml. Spreaded out over 12 hours with a dosing pump on my 60 gallon tank and seems to be be lowering my PO4 and NO3. I’ve been doing this for the last month or so. Is it normal to see this algae with carbon dosing? It’s showing up the next day after a cleaning. These pics are after 2 days post clean. I’ve never had the algae until I started with the vinegar dosing.

What are your photos and nitrate levels? it could be dinos. They thrive in low-nutrient environments (because you are carbon dosing).

This was 2 days ago.

I would not refer to that as algae without a better picture. Not sure what it is (cyano? dinos? diatoms?), but carbon dosing would not be my recommended way to deal with cyanobacteria since it can really consume added organics, and organic carbon dosing often spurs cyano.

Here is some better pics of the algae with my parameters over the last 4 days. I never had any of this algae problems until starting the vinegar dosing and I’m thinking I was better off without it just doing more frequent water changes to lower nitrate and phosphate. lost my foxface yesterday and my flame angel today, they have been in there 1.5 years with no problems. I’m currently doing 15% water changes every two weeks on this 60 gallon. So to stop the carbon dosing I’ve heard not to just stop cold turkey but just taper down. Would do you think that rate should be. I’m at 20ml daily spread out over 12 hours. Also is the carbon dosing increasing CO2 that could have lead to the two fish deaths?
