Just out of curiosity.....
Has anyone been dosing levamisole for 1+ years and had good success with SPS?
Reason I ask is I get quite a few emails and PM's daily concerning how to solve issues in SPS systems. Most are easy fixes and in a couple months the systems are back up and doing well. But, I have had six reefers who no matter what we tried were unable to get the SPS healthy and growing again. It turns out that the six tanks were all dosing some form of levamisole. These tanks all shared the same problems of bleaching at the base of SPS and little to no growth. A couple of reefers have since turned their systems around by running large amounts of carbon, polyfilters, and purigen in order to remove any residual levamisole. Unfortunately, three of the systems that were dosing levamisole have since crashed.
So, I was curious if anyone else has been having issues with SPS since start up of levamisole ?

Sonny,
My main system which was a part of this trial had various forms of SPS of hardy to delicate. I didn't use any flash and mirrors IE dose differently from what I posted. And I lost 2 frags which I had duplicates of already at the time of dosing. I dosed for 4 weeks as a preventative to insure I got the planaria in what may be a reproductive/dormancy cycle. Since we do not really know thier cycle or the site for their eggs. Now, the SPS are growing. The planaria are gone. That's my long term experience with it thus far on a systemwide or in tank dosing.
Now, I treat all incoming corals,frags, nems, anything really. With a levasole dip, iodine and interceptor. And if it's from a questionable source I just don't buy or accept the trade.
What I have noted in another trial I did on the levasole as a monty nudis eating eradicator was that the amount of levasole needed was enough to kill the patient. I'm going from memory here, but I think I was at the 5ml per gallon point which slowed the monty mudis down but zoas were oozing and the montiporas were sliming which led to a total kill in the 20 gallon by the next day I tested the stuff on.
Therefore, I would guess that continual dosing of levasole could impact not only SPS, but the whole micro-ecosystem of a captive reef. I didn't run a continued dosage scheme so I do not know for sure what that would do. But my GUESS is that the virtually unknown longterm or method (in the organisms? The substrate? In the rock? Bond in solution with something else in saltwater?) by which levasole would store or accumulate in a system would be a harmful thing.
IF there was continued dosing of the levasole? Well, I would kinda fall on the side of going from the common sense of things in this manner. Levasole which is a cheaper substitute for the salifert stuff causes the worms to melt. Kinda like salt poured on slugs which alot of mean little kids out there used to do.
Levasole must either directly attack the outer skin or whatever the dermal layer of a planaria is called. Or it's absorbed by the animal and it disrupts the internal cell membranes in the planaria possibly by an osmotic shock and they melt because the membranes explode and maybe that's why we see them melt away while they are moving. Just guessing. But if either of those are the means by which levasole nukes planaria then one can make a leap to believe that somehow, someway it would impact the same on other things in a tank under too high or long term continued dosage. And on the side of horse sense. If the doctor gives you amoxycillian for a virus and you kick the virus in 10 to 14 days and you continue to take the amoxycillian...well I'd think that would be kinda bad for you.
Anyway,
What I do know is that a mild dosage with my initial recipe under the duration in the planaria trial cured the system of planaria. And things have never been better.
Just thought I'd chime in with my thoughts on the stuff.
Mike.
