STN/RTN from ROX Carbon?

[natas]

I changed out my ROX Carbon this morning (been about 1 month) and my Red Dragon colony started to lose tissue at the tips around 6 hours later. I was wondering if its possible that this event started because of the Carbon change. Maybe it cleared the water so quickly that the coral was shocked by the lighting (been slowly acclimating to a high intensity with my LED's).

ALK and PH are stable. ALK is exactly where it was two days ago. (I test every 2-3 days)

I have been watching it closely the past 2 hours. So far I haven't seen much change since I first noticed it.

It is very powerful stuff. I use 2 tbs on 260 gallon system.

Do you see change in water clarity?

What? 2 tbsp on 260 gallons....that must be a typo. Brs recommends 26 for 260g

Yeah it did. In fact I was admiring the difference and that's when I noticed the coral. I usually change at 2-3 weeks but kids and work delayed me 2 weeks so the difference was more noticeable than normal.

Not a typo. Use Google. There are many threads on this subject in this forum.

Wow. I have always known it to be strong which is why I usually do 3/4 to 1/2 the recommended amount. Maybe I should go 1/4 for now on.

I was always nervous changing carbon and GFO (even when rinsed appropriately and used sparingly) on my old system because of this type of thing. Your are probably right it was the carbon for one reason or another. On a number of occasions I had issues such as this, as well as base recession, after swapping out. Carbon if there are any small particles can cause physical irritation, especially if blasted through high floor. I eventually took carbon offline altogether, and on my system use neither GFO nor carbon, and have never looked back. Actually, I've got tons of BRS carbon that I should give away/sell.

I hear ya jroovers. I killed some SPS's in the past with the High Capacity GFO from BRS. I went with the recommended amount and the next day had about 5 sps's RTN'ing. That stuff strips Phosphates quickly if using the amount they recommend.

I never thought Carbon could do this, but I blame myself for taking so long to change it and not researching.
