I'm runnig my system without any carbon or UV. It's been running for about a year with no problem at all. Should I put some carbon in it or start running UV ?

your system will run w/o carbon, it's just a good way to clear up your water and filter some crud. Difference, I have two sw tanks in my office, 1 has no carbon and the other does, 1 w/o it has the lightest hint of nonclarity, while the carbon ran one looks like the fish are swimming in air, seriously, you cant see any impurity. Tho I think I'm going to try the purgen and run carbon for a week out of the month.

this is easy, don't run carbon and you don't have to worry about it

Guys,
I've been running carbon for 2 weeks and noticed my ph decreased by .2 - .4. Is this normal?

Some forms of carbon are treated with phosphoric acid as part of the manufacturing process. This is why some forms will release phosphate into a water column, in particular, carbon made from coconut shells. These same brands will usually release protons into the watercolumn, causing the pH drop you're experiencing. Look for a brand that does not release phosphate nor cause these transient pH fluctuations.
You can test the carbon by placing 2 tablespoonsful of the carbon you want to test (about 30gms) in a pint jar of distilled water (~500ml distilled or RO/DI water), cap it , then vigorously agitate the container for about 5 minutes, then allow to rest for about 2 hours and test the water for phosphate and/or pH changes. You may need to test some of the water you use for this test without any carbon in it to assure that your source water is free of free phosphates. Any detectable results is cause for discarding the carbon for marine aquarium use,
