Hi,
I have a fish in hypo and he still has lots of white spots after 2 days(1.009sg). Is this normal or should i be thinking it's velvet instead of Ick? I have some cupramine but i'd rather not use it if i don't have to.
 
I am doing hypo as well,from what I have read the spots could take up to 4 or 5 days to clear off,mine are on day 2 and still have some spots.
 
I saw in another thread that you are doing hypo in your dt. Won't it kill all the good bacterias in your lr and sand ? I'm tempted to do the same.
 
Hope it goes well for you. Are you doing hypo for Ick or velvet?

Hypo is not effective at eliminating Velvet (Oodinium). If you are dealing with velvet, not ich, I'd change treatment ASAP. Velvet is a much faster spreading (and killing) parasite than ich. If you Google both; you should find several good descriptions of both and decide what you are dealing with.

Exactly. I have blog entries on both that may be helpful.
 
Took another good look at my fish and it looks more like Ick. He's doing better since he's been in hypo too. Eats lots of garlic soaked nori and some frozen plankton. I guess if i was velvet, he's be dead or close to death by now. Think so anyway.

Quite possibly. IME: the easiest way to recognize velvet is looking at the fish head-on. The effected large areas of skin seem more obvious that way. Fish with velvet will develop a filmy slime on their skin; some sources may say this slime takes on a "golden' or "velvety" appearance. Don't count on this with SW velvet, just watch the skin and spots. Fish with velvet are almost always "sicker" than fish with early-ich. More lethargic, hang around the surface, heavier breathing, they also seem to stay directly in the water flow for long periods. But, the skin coating is the big thing, IMO. Velvet appears as almost a hybrid of ich and brooklynella.
 
He's still doing well today. I don't see any coating or slime on him. Just lots of white dots. He's still a bit shy(new fish) but was swiming more today. He never tried to swin the the powerhead's flow or hang around the surface. But he still has lots of white dots on him today. Still eating well. Not breathing so fast today.
 
Don't worry too much as long as you are sure it's ich and you are administering the hypo correctly (measuring the salinity with a good quality refractometer and not a hydrometer).
Ich goes through cycles and it tends to stay on the fish's body for a few days before falling off. Once they all fall off, wait for another 4 weeks and if you don't see any more white spots during that time, you should have successfully battled ich.

IMO, 4 weeks is not long enough. http://www.reefcentral.com/forums/showthread.php?t=2041951
 
I read that article too. I was just going by conventional recommendation of 4 week observation post-treatment. In your opinion, how long should we observe? 3-sigma is 99.7% so maybe we should observe for 9 weeks then?
I've started 9 weeks with new fish. I have the patience to do that now, that wasn't always the case.

I agree with you. I have more patience than when I first started out in the hobby. Though, I'm not sure if I have enough patience for 9 whole weeks lol...
 
Just a few white dots today. He's still doing great and eating well. Yes i use a refractometer and i have an automatic top off system on the QT tank. I still check the salinity every day just in case and it stays right at 1.009. I have been in the hobby for about 6 years now. I've seen Ick before but never quite like this time. That's why i was thinking it might be velvet.

I have patience, i was just affraid it might have been Velvet and then, waiting would not have been a good idea. I had Cupramine ready to use LOL But now i'm pretty sure it is Ick.

If it was velvet, fish would barely be alive by now----but there are exceptions to everything. IME: the best way to spot velvet is looking at the fish head-on. The fish's skin will obviously have a coating, not just the white salt-like grains of ich.
