Materials that react with CoralRX

[javisaman]

Hi,

Recently I had some corals shipped to me, 3 sps and 1 zoa. They came in a very nice ABS plastic rack, holding 4 frag plugs. I always dip my corals in CoralRX, followed by another dip in clean saltwater with hydrogen peroxide, and visual inspection. This time I used the rack to dip it into the CoralRX solution and within 15 seconds all of the SPS RTNed. The flesh literally sloughed off; I've never seen anything like it. I was wondering if anyone else has experienced this before. Or if they know of other materials that potentially interact with CoralRX. I've been using the same bottle for months without issue, and it's still within the expiration date.

I haven't heard of this happening myself. I'm not trying to say some reaction didn't happen, but have you considered that the corals themselves were going to slough off, independent of the frag rack? To me, occam's razor would suggest the fault lies with the health of newly shipped corals, and not necessarily a possible chemical reaction. I'm not saying one didn't happen or isn't possible, but it would be a distant consideration. For example, you can dip SPS in pure bleach and you're unlikely to see tissue sloughing in 15 seconds- this suggests the tissue was already deadhering in transit.

I don't use CoralRX, so I can't do the test myself, but if you have any "sacrificial" sps in your tank, you could always repeat the dip with the frag rack and confirm whether a reaction is taking place or whether those newly-shipped SPS were doomed from the beginning. If your established sps immediately RTN/slough off, you would have a lot more evidence on your side. Until then, they died in transit

That had nothing to do with the CoralRX

those corals were just gonna do that regardless.
sounds like either bad shipping or unhealthy corals to start before shipping.
