Display tank: 150G custom tank + 50G sump. started from August 2019. Some of the rock was from the old 15G nano started from July 2018.
QT tank: 20G long, established after the velvet outbreak for holding fish purchased from the boxing day sale... However more like an observation tank.
Some background: first sign of velvet discovered in DT around Nov 2019, after adding a ruby red dragonet (died two days after introduced), then one anthias started to show signs of velvet, and died the next day, another anthias followed, and a swallow tail angel, and a convict goby, a clown goby, a hippo tang died in next few days. What's left were one clownfish, one convict goby, one anthias that had obvious signs of velvet and survived, and a orange shoulder tang and a diamond goby that never got infected.
Then no fish were introduced to DT for about one month, no dead in DT during that month.
Since I am in Canada, I am not able to buy any effective medicine to treat velvet. So I am kind of giving up and hope for the miracle......
Then I added a bicolor blenny No signs of velvet.
And I purchased a Kole tang and put it in the newly established QT for observation.(At this time, I was trying to pick up the habit of QT), added to DT two weeks later without signs of velvet.
Then purchased two small tangs (hippo and purple) during the boxing day sale and put them in QT. Keep in mind that I was still using the DT water for QT, which means QT still has velvet.
Three weeks later both tangs in QT showed signs of velvet. And realized that I was still dealing with velvet.
Then I found some one using H2O2 treating velvet with success. So I purchased a bottle of 3% H2O2 from Walmart.
However, I got the dosage wrong for the first couple days in the QT. I was dosing 240ml/day of H2O2 in QT(20G), 120ml in the morning and 120ml in the evening, the sign of the white dust was reduced, but the color of the tangs were pale, thats the time I realized that I was dosing too much, then I reduced the dosage to 120ml / day, white dust was gone but color was still pale. Then I reduced to 80ml /day for next 5 days and all the signs were gone. Then I put them to the DT since I feed a lot in DT, hoping they could recover better.(I was not feeding much in QT because of the bio load)
Meanwhile I was also dosing DT 60ml/day. No signs of native effective on corals, however some copepods died right after the dosage.
Two days of them being in the DT, you guessed, signs of velvet showed up, but with my doubt, the signs looked like Ick as well(you guys can help identify in the following pics). But I kept dosing H2O2 in DT but with 90ml/day, 45ml in the morning, 45ml in the evening.
The pic were from the time both tangs showed signs of velvet or Ick.
Day 1 of them showing signs:
Also the time I started to dose 90ml/day.
