So I am dosing at 15mg per liter at 1.09 sg. After I mix the QS I have a lot of powdery residue. Do any of u throw the residue in or just use the dissolved parts?

You are using QS & hypo at the same time? Not a good idea, too much stress for the fish. QS is hard to dissolve and to keep in suspension; but, sure, add the residue---its part of the measured dose.

I agree, get the s.g. up. I use a pop bottle to mix QS, shake well, add entire contents.

Is QS most commonly used for treatment of ich?

No. I would say the most common med for crypt is copper, like Cupramine or Coppersafe. Treatments like QS or CP (chloroquine phosphate) are generating somewhat of a following since they are gentler on the fish and easier to dose (e.g. CP is a "one and done" treatment).

I think the question was directed asking if ich is the most common thing treated with QS.
Yes, but effective against velvet, stubborn flukes and possibly brook and urenema as well.

Oops...you're right. I misread the question!

I'm not sure about 1.09 but doesn't a lower salinity allow the fish to 'breathe easier'?

It used to be very common to keep fish at about 1.017, but this isn't done much anymore. The main reason was that the lower SG water exerts less pressure on the fish. Many vendors keep fish at a low SG (say 1.019) for several reasons. I know folks who swear fish are more active at a lower SG.
But this thread is about curing ich with very low SG and 1.009 is way too low to keep fish long-term.

Well had to change things a bit. Blue tang stopped eating and swimming on day 3. Just layed on the sand constantly. Re-Infection rate was way too high. Started doing daily 20 percent water changes at 15mg/l QS daily. Tang is showing marked improvement. Sailfin down to only one spot on him. Now if only the blue would start eating again soon. Might have to take them out of hypo sooner than I thought to see if I encourage her to eat.

So is QS considered to be a 'substiute' for CP? I'm a bit suspicious of the quality of the CP I have on hand (plus it is about to expire) and bought a small tub of QS in my most recent order form National Fish Pharm.

I have read anecdotes from forum users that QS is a bit more harsh on fish than CP, but it is just as effective.

QS has half the life as CP, and in order to work best it MUST be dosed daily. As far as more harsh, I've yet to experience. I've treated fish with both CP and QS.

Good to know. How long do you typically treat with QS? NFP recommends treatment for 7 days, but I don't see how that would be long enough unless it kills the tomont stage.

Funny, this thread pooped up.....I was going to PM Mrscribbled on this question.
I'm a die hard copper user but have used both QS & CP on other people's fish.. Those fish weren't going into my tank until I was sold. I'll usually be using CP from now on. CP handled velvet and ich very well and neither parasite has shown up in the owners tanks for at least 6 months. I'd be careful where you buy CP. I'm not positive on the regs surrounding it and am convinced that it is being cut with by some shady vendors. A friend, who is a chemist at a SW aquaculture lab and A-1 reefer has found baking soda in a CP sample. An absurdly low price tipped her off.

FWIW, on my bottle of QS, for a 20 gal tank, instructions say to dose daily at full strength for 10 days minimum and that it will kill all stages of ich.

There are a number of similar reports from users in the big CP thread in this forum. If you aren't sure of the quality, there's always the option of getting your local vet to write a prescription. I have a great relationship with my vet, and he was happy to write a prescription, which I filled at a local compounding pharmacy.
As I've mentioned in the CP thread, it sure would be nice if one of the mainstream vendors would start offering CP with a guaranteed analysis. Then we might have some consistent treatment protocols.

Yes. Should go full 14 days, and perform the water changes. I've also gone the daily dose with only doing water changes every 5th day. Did loose one eel during the later treatment.

Interesting. I may pick some up and give it a shot next time I have a fish in QT with active infection. If it will eliminate ich in only 14 days, that's a major plus in my book. Even better that it destroys all stages.

Good idea. I'd guess, that because CP is a med that requires a Rx from a vet, marketing would be impossible.

True. However, metronidazole is also a prescription med for treating protozoan diseases in cats and dogs, yet we can buy it "over the counter" from NFP. I think the financial hurdle of getting a new medication approved for ornamental fish is the more likely barrier.
