Carbon does remove some trace elements but if you are performing regular water changes this shouldn't be an issue. I run carbon 24/7 to keep my water crystal clear and combat any toxins released by corals. Keeping the carbon in too long can result in Phosphate being leached into the aquarium not nitrate.
If you don't run it 24/7 I would run it for a few days each month as a part of your tank maintenence and then run it additionally if you are having problem with corals opening or if your water takes on a greenish or yellow tint.

I also have a hippo that has been in my tank for two years and have been running carbon 24/7 for the entire time. I really can't see any basis for this claim carbon does not release anything back into the water unless it is left too long then it will begin to leach phosphate.

Quoted out of the disease forum;
Activated Carbon
There is plenty of anecdotal evidence suggesting that the use of activated carbon in filters is a causation of HLLE in fish, particularly tangs. It is purported that HLLE can result when carbon particles leech into the aquaria, or the leaching of organics filtered by carbon, or by the removal of essential water elements by the carbon’s mechanical filtration component. Whatever is the cause, animals prone to HLLE kept in aquaria that relies on natural filters, such as sandbeds, live rock, refugium systems, macroalgae or mangrove tanks and good water movement throughout the system, usually remain healthy and free of HLLE.
That is not to say that hobbyist should throw out their canister filters. Rather, that if HLLE erosion is an issue in your system, or if you plan to keep fish prone to HLLE, then use carbon sparingly rather than constantly. Use it for a few hours occasional to polish the water, not a constant exposure. Natural filters, regardless of disease considerations, is always a healthy choice for captive marine animals.
I have seen similar warnings before this one.

I have not read this before, I stand corrected. I have never had any issues with HLLE though either.
