I feel like I’m posting in here every week lately. But now my Large Blonde Naso tang has these black marks on him. Couldn’t get pictures so I took this video. His breathing is a little more rapid than lately. I stopped treating my system with metro last Saturday and have been dosing H2O2 at 1ml/5gal since then, running carbon and UV at parasite control levels. I’ve also been soaking the frozen food and pellets in general cure, Focus, and selcon. Feeding twice a day.

Tough to see, but the second video gives some indication of spots on the fins, and then on the body when the fish turns sideways.

Neither Metronidazole or peroxide (as a static bath) give good control for protozoans, and no control for flukes. Soaking food in GC is also not appropriate (getting the dosage correct requires a lot of calculations, we have a program that does that if you check the fish disease forum stickies at the top).

My fear here is the spots look very small. You mentioned the fish is breathing a bit fast. That *could* be symptoms of velvet. Your tagline says you have a 480 gallon, so I hope that isn't the case.

No symptoms on any other fish?

Hey @Jay Hemdal ,

yes I do have a 480 display. I was dosing the tank for a week with metro due to the outbreak I had and stopped that last Saturday. Last night when I took the videos he was eating fine and swimming around. All the other fish are looking much better from what was going on previously. I don’t notice many white spots at all on any of the other fish. And I have the Scopas and purple tangs in there as well.
 
As far as the peroxide goes, I’ve been dosing 110ml every 8 hours and running a 114w UV at 1300gph
 
Can’t see video on my phone but seems Jay has a grip on this
Peroxide dose seems high and likely not a cure for what you describe

I’ve been dosing the peroxide in relation to Humble Fish's guidelines. It’s a 600 gallon system

In a 660, I use ruby rally pro for most issues and quarantine for coppersafe.
im familiar with that recommendation which was from 2016, not to say it’s ineffective but other methods have been presented since then
 
Copy that. Is Ruby Rally reef safe? would I be able to dose straight into the display?

My problem is I can't remember all the other things you've tried. I also cannot see the videos. But - my comment would be - the metroplex - not sure what you're trying to treat - and 2. the UV and peroxide are probably not doing much - if anything for any of this. Mainly because UV causes rapid degradation of peroxide. And unless you have a HUGE UV - for a 600 gallon tank I am not sure its going to be effective (many people will suggest it is not effective for parasites anyway - not sure I agree with that statement)

EDIT - Carbon also removes peroxide rapidly.

Also, I did one week of metro dosing straight to the tank. After that week, I did a 150 gallon water change, started carbon to get any other medication out, and then started dosing peroxide and UV. This has been going for the past week now.

This is where I’m getting my information from. Research done back in 2020 on the effects of peroxide dosing and UV and how it actually helps UV. https://humble.fish/community/index.php?threads/peroxide-h2o2-dosing-for-parasites-in-reef-tank.725/
I’m using a 114w UV and using the suggested flow rate of 1300gph from Aqua Ultraviolet for parasite control.

Thanks for the information - and I've read that article:

I was going to go through and quote some points, but I figured it was a waste of time. One key take home - She was dosing H2O2 up to every 1.5 hours all day long 'in order to maintain levels'.

Second - UV and Peroxide are generally recommended for 'prevention' - as compared to treatment of active disease. BTW - I don't consider 1-2 spots as 'active disease' - it just seemed like yours was 'more active'.

My caveats, I think, were true - Both Carbon and UV cause more rapid degradation of H2O2 (which is why in her tank she had to dose so often)

From a different article article: " Depending on the initial dosages, the H2O2 added to the system can be completely decomposed by UV within 50 to 90 minutes."

BTW -- I'm not a water treatment 'expert' - my guess is that they are adding H2O2 directly 'in front' of the UV - to maximize both. It is my OPINION - that most of the H2O2 added to a display tank is rapidly decomposed by all of the organics. (Since she mentioned that in a water treatment plant , they use UV and Peroxide - I brought this up).

BTW - I'm not trying to criticise you or your method - only commenting on why it does not seem to be working as well as you would like.

Different organic levels react to peroxide dosing as well, and this changes over time! I would never dose peroxide without using a LR test strip to monitor unreacted oxidants.

For my information - what is an 'LR' strip?
