I used 1/2 of 23mg for a 100gal tank.Is 24hr too long to treat fro?

I dont think it lasts 24 hours. I think it degrades in salt water faster than that.

Actually it seems to last quite a while in seawater Rich. This is evidenced by people, including myself, putting hermits back in several days after treatment with water changes and carbon run according to directions and the hermits dying fairly quickly.

IMO there is no reason to treat for that long but we may be doing that anyway and not knowing it.

FWIW, Chris

Wierd, I put hermits in the next day last time I treated, had no problems. I never did any water changes or added carbon. I turned the skimmer on at about hour 12.


I used one of the small dog pills (15mg, IIRC) in a 58. Thats two or three times the reccomended dosage.

I had a discussion with Calfo about this. I assumed Interceptor [Milbemycin oxime] was an antibiotic, after all it's prescribed for dogs. The name is a little misleading too, ending in -mycin like erythromycin for example. Turns out it's classified a pesticide :eek2: So you can't count on it's "medicinal" value degrading like an antibiotic... it could remain active in the water/system for much longer.

My experience too. After 8hrs. the crabs went back in, they were a little sluggish for several days but ended up fine. One crab I missed, he came crawling out of the rocks after about 4hrs of full interceptor treatment. I pulled him out and then replaced him with the rest of them, he ended up fine too :confused:

im trying to get feedback on the following question: Has any one treated there reef tank with inteceptor and noticed color loss and or loss of growth? Im not talking about moving corals out to qt tank and or dipping them. Im just curious about doing one treatment in tank, how does color hold up?

Well I guess my experience is not as widespread as I thought it was. Did you guys that didn't have problems with hermits have sand and treat 3 times?

I actually had better color and PE because the little buggers weren't aggravating the acros anymore.

I have a DSB, and only treated once.

Don't worry man......it will be fine. I did the treatment 3 times and didnt even lose my anemone crab. I had a friend who did it for 2 days and his corals came out awesome

if you only do one treatment it should be fine but i didnt lose any hermits and shrimp to the last treatment (3rd) and it wasnt untill the next day that i lost any of them

nashorn

So far so good. I post some pictures soon. Looks like no color lose at all.Seem like some coral even colored up more.
Next step would be to wait a few days and do one more water change 30% and then wait 2weeks(anyredbugs in there should be dead by then) and put the sump(with liverock) and refu back on line.I didn't nuke them so I won't lose all my pods.

I have been wondering how long this stuff stays in he water myself. Id rather not mess with the carbon if i dont have to.
I also have a DSB in the system. The hermit that got left behind in the system died within an hour and it also took out a emerald i missed.

I lost my emeralds when I treated, or in the following week or so.

Good to know Mark.....I am thinking that maybe the fact I had sand at the time and treated 3 times (lots of people seem to want to get away with one treatment these days) has to do with the hangover effects. I have no way of knowing at this point though. All I know is when I put my hermits back in a couple of days after the 3rd treament they all died fairly quickly. And I did all the water changes, ran barbon and only deviated fron Dustins directions in that I used a 110% dose for the 2nd and 3rd treatments. As far as in tank I killed a gorilla crab I had been trying to kill anyway and lost my cleaner shrimp.

I found that the interceptor does not kill most crabs untill its 5th-6th hour.Found some alive untill then and were able to fish them out.I had a arco crab move out of it's coral 8 hrs into the treatment(saved it too)
So I can see why redbugs can hang on for a long time and why the old method of 6-8hr did not kill them all. I hope I got them all at 22hrs.I'll keep all the crabs in my refu for 2 weeks before moving back to the tank.I have a DSB and keep sponges and sea squirts and they seem fine.

I removed all hermits, shrimp, etc. And dosed for 12 hours. I did a water change, then immediately dosed again. This time I left it in for a week until I ran carbon and changed water. When I put my acro crabs back in they died. After a few more weeks of regular water changes i reintroduced the shrimp and hermits and everything was fine. Both times I purposefully overdosed.

Used 1/3 51-100lb dog tab on my 110g. Turned skimmer on after 8 hrs and ran carbon. No water change. All red bugs are gone, a few hermits died but all the larger ones survived along with all my porcelain crabs, interesting I must say.

nashorn
04/22/2007, 01:40 AM
Hmm...I wonder ifthe brittle stars made it? I haven't seen any lately or they may just be feasting or all the dead pods and other crabs.

fishdoc11
04/22/2007, 07:20 AM
Brittle stars should be fine....Milbemycin oxime only kills nematodes and arthropods...at least at lower dosages.

FWIW and JMO but it's good to be cautious about the success of Interceptor treatment for 6 months to a year after treatment. Many people have treated (less than 3 treatments) only to have the bugs come back several months later.

What are you testing with an Astrea?

aquarius77
04/22/2007, 06:14 PM
Im testing to see if its going to kick the bucket from the interceptor that i never really made any attempt at getting out of the tank. Been skimming and chaged water 2 different times but no carbon.

I think im going to change my water tonight and try a hermit tomorrow.

Interceptor doesn't kill snails which are mollusks. Like I stated above, it only kills nematodes (basically roundworms) and arthropods (crabs, shrimp etc...)

What dosage did you use?

fishdoc11
04/26/2007, 05:21 AM
aquarius,
I would suspect that the fact you overdosed and let the meds sit in the tank as long as you did were factors in killing your nassarius. The fact they live in the sandbed and there was likely dieoff there was probably also a factor. With proper dosages snails are not effected. Nassarius snails might have something in their makeup that makes them more susceptable than Astreas, turbos etc......but habitat (living burrowed in the sand) and dosage/duration seem much more likely to be a causative factors in your case IMO.
FWIW, Chris
