I didn’t read through everyone’s replies, but I’ve had really fast success on 2 tanks by dosing hydrogen peroxide (1 ml per 10 gallons), combined with a UV sterilizer running at the higher flow rate. On one of those I dosed microbacter7, not sure if that helped anything. Both tanks, dinos were gone in 2 days for the most part.
On both of those tanks, I had no phosphate reading. Once the dinos died, my nitrates and phosphates shot up.
I had another tank that I was able to dose phosphate and once I got a reading I did a 3 day black out. That also worked but not as quick.
