I dosed metronidazole at 250mg/10 gallons daily for 10 days and it cured my Dino problem...hooray!
But by day 8 I had an RTN event that killed all of my SPS within 3 days...moan!
I can't blame anything but the treatment for this, so proceed with caution. All of the corals were doing well till this happened and parameters have, and continue to be rock solid stable. SG 1.025, ph8.0,ca405,dKH 8.0,po4 0.04, nitrate<1,mag 1380.temp 80.
Same thing happened to me, but my p04 spiked, interesting to see yours didn't.
Should I remove zeolite when I use bleach
Ok, time for me to weigh in with an update. I did the initial 3-day metro dosing and waiting the however many days (was it 10?) after with daily removals. It did seem to clear things up a bit, but they always came back, though never as bad as before I started. I let it go maybe a month after this with daily removals and things did not get better. Then I did a 10-day regiment of H2O2 2x daily, which again, not sure if it helped (as it never helped before), but continued with daily manual removal and then I added some pods. This may have been the tipping point in outcompeting and killing off the dinos, as I started getting less and less in my manual removals. Then I started to get a little bit of cyano (which I took as a good sign in that the dinos were dying off). I did one bout of chemiclean and things looked good. I then added even more pods and no longer needed to do manual removals. A little bit of cyano came back a few weeks later and I did another round of chemiclean a few weeks ago. Things have never looked so good in my tank! I sent twilliard a water sample and he said he saw no dinos! He did note that my biological life was limited probably due to my H2O2 dosing and 2 rounds of chemiclean. I'm considering dosing some Dr. Tims to help build my bacterial population back up. Nitrates are a little high (25 ppm) whereas they are normally around (2.5-5 ppm), which kind of confirms the lack of biological life. Pictures to come.
Again, thanks twilliard for all your work on battling these dinos. I still believe the initial metro dosing helped kickstart all of this. Although not completely effective alone, after another round of H2O2 and adding pods, it seemed to eradicate them in my tank.
metro dosing...ill have to look that up as i don't know what it is.I turned off carbon during H2O2 dosing and during metro dosing. I kept my lighting schedule the same. I did not want to do a blackout. For me, I think what led to success was the 3 days of dosing metro, daily manual removals with turkey baster and filter socks, 10 days of H2O2 dosing 2x day with continued daily removals, followed by addition of lots of pods. Biologically it seems to make sense as the metro makes them unable to reproduce, combined with the daily removals, combined with further killing by H2O2, knocked back their populations, then the pods outcompeting them was the final punch for these guys, knock on wood.
