Instructions say 60mg/g. Seems a bit much no? Also, doesn’t specify if tank can have live rock during dosing. Will the rock absorb it like it does w copper? I’m at a loss here. Any info would be helpful. Thanks

That works out to be 15 mg/l which is a pretty standard dose.

I would use it in a sterile tank as certain bacteria "eat" the medication or render it ineffective.“Using it with live rock will lower the quality of the rock but it Jay”?
I will look up the article thanks. But I’m in Canada and there’s a sweeping ban on all kinds of meds here. I got lucky and ordered from the US a while back before the ban.
I wanted it for use w tangs and a watchman goby. They don’t do well w out algae and live rock so Chloroquine Phosphate is a really good alternative to copper. No inverts in qt to worry about.
Thanks!I would use it in a sterile tank as certain bacteria "eat" the medication or render it ineffective.
Sorry - I was using my phone and that was a typo. I meant that Chloroquine will kill off any invertebrates on the live rock, rendering less "live" and more "rock".“Using it with live rock will lower the quality of the rock but it Jay”?

While that's true with praziquantel, I have a UV spectrophotometer, and can measure CP in solution and didn't find that the concentration dropped off very fast at all - over weeks as opposed to days/hours with prazi.I would use it in a sterile tank as certain bacteria "eat" the medication or render it ineffective.
Interesting. In the past, I've qt'd with CP with no biofikter established. Just clean tank, and prime daily until ammonia is no longer detected. No w/c, no "top up" dosing. Never had issues. Now, I'm being more careful about doing w/c and dosing back that amount, etc. I guess I'll stop worrying as much about degradation. I've seen mentions that even 20mg/gal. Is effective, so if one starts at 40mg, how long would that last with a strong biofilter present?While that's true with praziquantel, I have a UV spectrophotometer, and can measure CP in solution and didn't find that the concentration dropped off very fast at all - over weeks as opposed to days/hours with prazi.

Well, it may be that some bacteria degrade it while others don't and the results depend on the bacteria strains you have in a given tank. People have had mixed results and there were some reports where they tested it also with a spectrometer and, as I recall, it was found degrading. So I think there would have to be a much broader study done to come to a definitive conclusion.While that's true with praziquantel, I have a UV spectrophotometer, and can measure CP in solution and didn't find that the concentration dropped off very fast at all - over weeks as opposed to days/hours with prazi.

I’ve never used it as low as 20 mg/gallon, so can’t tell you if it works well or not.Interesting. In the past, I've qt'd with CP with no biofikter established.

I agree, the CP should still be at the treated dose after only two weeks.Well, I treat them 10-14 days at 80F and transfer them to a clean tank. The treatment tanks are heated up to like 108 for a few hours (104F for an hour is minimum) between batches just in case. I run it hotter and longer to account for any "cool spots." That keeps the biofilter intact. And should take care of any Tomonts. 99% water change on treatment tanks before starting a new batch. Cp dose split up to 2 doses of 20mg/gal. 24hrs. Apart. After a 2 day period of settling in with no meds. So, I imagine in 10-14 days, the chloroquine concentration should not be degraded much.
Great article, thxThat works out to be 15 mg/l which is a pretty standard dose.

Hello Jay,
That is a pretty high dose for CP. I started seeing fish toxicity at that dose - wrasses and lion fish for sure, maybe others.Hello Jay,
Thanks again for the article. I’ve recently been advised by my QT Marine vendor that they recommend 80mg/gallon with 10-15% redose every 48hrs.
I’m doing the 80mg dose w/ re-dose to an established QT (was green algae on rocks) which is more like a new DT.
40 gal breeder w/ 20Long sump. Here on day 9 all green algae has been gone. Water was cloudy until day 8, did a 15 gal water change ( w/ CP) on day 6.
After reading your article, and with all algae dead and gone I was thinking about dialing back upon the re-dose. I’m planning to have them in meds for 30 days.
What are your thoughts on dialing back to maybe every 4 days to redose, or more?
