Kent Tech-M killing Zoanthids?

[Beefy_Reefy]

So I'm dosing Kent tech m from 1260 to 1800. I'm raising 100 a day, give or take a few. I've tested everything else and all is perfecto. I do have to remove some tank water and let the ATO fill with RO because the Mag is raising my salinity from 1.025 to 1.026/1.027... I'm currently at my target point of 1800 and have already lost a Pally, zoanthid and 2 more zoa's looking like they are shriveling. All moving inverts are fine. I thought zoa's were hardy.... SPS, LPS all fine. Is the mag really causing the problem? All other tests come out right on the money. Alk is 8.0 low side. But always is. I dunno... I really want to get rid of this bryopsis.

Hmm, that's fairly high. I haven't heard of zoanthid problems before, though. I'd probably try some water changes to lower the level. It's possible that the active agent in Kent Tech-M is some contaminant, and the high magnesium level doesn't make a difference, anyway.

 

[Randy Holmes-Farley]

I've not heard of it before either, but it wouldn't surprise me if the Tech M brypopsis method is not exclusive to bryopsis killing.

I think the whole method is a shot in the dark. If it's not the magnesium level or effects from it then proponents are betting on some unknown toxic impurity of unknown quantity in any batch of the Tech M. The perceived effect on bryopsis could be a placebo or related to the toxin . If it's the later I don't know if I'd be firing a small bullet or a cannon ball since I have no idea of the quantity of the mystery impurity , nor do I know what it's going to hit.

So after 10 days of Mag at 1700-1800 all I got was some dead zoanthids/palys No change on briopsis yet. I think I may just quit the Tech M... Something isn't right.

 

[bertoni]

Well, I'm sorry to hear about the dead corals. I'd probably do some water changes and work from there.

I tried the tech m for bryopsis, it worked for awhile then the bryopsis started to build a resistance. At that same time my zoa lost color and I stopped the tech m. This was a gallon of tech m in a 30 gal system.. I cured my bryopsis by scrubbing the rock with h2o2.

So post pics of your tank and bryopsis. People are just as unreceptive to peroxide as they are tech m, just wanting pics at this point not a technical battle, yet.

 

[agruetz]

I wonder if that is what caused some melting of my Zoa's. The bryopsis will definitely build a tolerance if you do not get it all the first time. I finally just fragged everything and stuck all the rock in the sump with no lights for about 2 weeks.

This thread is about zoanthus and tech M not peroxide unless you thin peroxide is in Tech M. Stop hijacking.
The characterization as unreceptive to anyone who delves into the rationale and chemistry and biologiy or disputes extrapolations and perceived outcomes and risks of a particular method is unwarranted ,untrue, and offensive.

 

[brandon429]

Where I was heading was we can kill bryopsis without killing the zoanthids. So, post pics of the prob. zoanthids are one hundred percent not ever harmed by it, its the one set of soft corals we have a total unaffected rate regardless of dosage technique...

 

[brandon429]

With pics, we can see if the infestation is local or not, for an external treatment...

I don't mean to bump an older thread, though thankfully not too old in this case, but here we are: I'm treating with Tech M for bryopsis and I have definitely dosed enough to see a noticeable die off of the bryopsis, which is now nearly gone. I'll say this with the disclaimer that I only have two softies in the whole system: my corals are visibly unharmed by the stuff and continue to show signs of happy, healthy corals. The one zoa frag I have is actually growing new polyps right now and opening entirely.

Is it possible that, given we don't know what the actual impurity in Tech M is, one batch would kill off certain corals in high concentrations but a different batch would leave these same corals completely unperturbed?

 

[tmz]

If it's an impurity , variability from batch to batch is certainly possible since no one is measuring it or controlling for it and don't know what it is or if it's there or not. As an example Kent reef carbon had metal impurities issues recently that lead to a number of tank wipe outs.
