HERE IS A INTERESTING ARTICLE.www.hallman.org/filter/gac.html
 
Don't use Kingsford or you will have problems. lol I have used Seachem Matrix carbon for years and i like how it polishes my water.
 
Like to here what others think about using carbon and those who don't.
 
Come on people lets get your opinions.:whip:
 
i use it but i have heard bad things about it, probably going to remove it soon, anyone have any good suggestions to a carbon substitute?
 
I have anecdotal but not scientific experience. Which is really only useful to me.....regardless!

I've always used carbon. My fish haven't ever suffered visibly, it is a good way to help keep some undesirable nutrient levels in check (nitrate!!). My new favorite is a carbon reactor from Next Reef. Same amount of carbon, twice as effective.
 
I've always used carbon without issue, and I've probably always used too much. I've recently added one of the 100ml of purigen alongside my carbon, but I'm wondering if I would be just fine with only purigen.

I do wonder if they shouldn't be used together in the quantities I have. I only have around 25 gallons of volume and I'm using probably half a pound of carbon and just added 100ml bag of purigen.

Thoughts?

I had an issue where it caused severe HLLE in my purple and sailfin tang. No other fish was affected but the purple never recovered and it took months to get the sailfin back into good health. The purple tang hung in for a few months but became so emaciated and colorless that it eventually got eaten by the CUC. The sailfin started to eat again and with some selcon soaked nori and frequent feedings it rebounded. I believe my problem was from not rinsing it well enough and the fine particles are what really hurt the fish. I was using the BRS premium ROX which is quite dusty and has small grains. When I switched to the cheaper lignite carbon it was easier to rinse and did not experience any HLLE.
 
I ran carbon for years with no problems. However, that all changed when Kent sent out some bad batches of copper laced carbon. Decimated our tank within 24 hours. Almost 8 months has gone by and I just hooked up a BRS reactor with BRS carbon and GFO. Time will tell.
 
I've used carbon from the beginning, i like it because if a coral decides to snot a tank I don't have to worry about it. Or if some other critter releases something. I've always ran mine in a brs reactor and use brs rox. I also believe people who have issues from it don't rinse it well or are using it in a mesh bag and it gets out into the water. I always rinse mine in the sink every change, then Do a five gallon water change running water through it before adding the return to the tank. If the water is coming out clear, I'll do another five gallon water change through it. I better knock on wood, but I've never had any issues from using it...but a the end of last year I did have a massive tank crash to 90% of my coral and anemones that I never figured out what caused it. I was running my carbon then and there was a recall on some...but I have no idea if it helped cause it or not. I still use it today, never took it offline to see if my tank liked it or not.
