Need to pump up my CYA, so I was shopping the local Walmart/Home Depot shelves for Trichlor Tabs. Is this the same thing?

No.
Tri-chlor is chlorine that release CYA as it is used. But CYA, called also stabilizer, conditioner or Cyanuric Acid can be purchased as a seperate chemical.
Tri-Chlor is chlorine in the form of tablets (or sometimes powder) that goes in automatic chlorinators or floaters. When you need CYA added to your water, they can be a good way to add it, because as they erode they keep a fairly constant level of chlorine in your water. But Tri-Chlor has another bug/feature: It's highly acidic and tends to drive pH down. If pH is low, it's not necessarily a good idea to use it, although you can compensate by adding Borax to raise pH.
However, if your chlorine levels are good and you are using bleach or liquid chlorine to maintain them, you can just use CYA powder by itself.
But many people run into trouble by using Tri-Chlor tabs in a chlorinator all summer without watching CYA levels. Their CYA shoots up and despite having what they THINK is adequate chlorine, they get an algae bloom. That's when we say STOP DON'T USE TRI-CHLOR ANYMORE!
So, if pH is low and CYA is at your target level (another discussion for another thread) or high, don't use Tri-chlor.
If, however, you have no CYA and your pH is trending high then Tri-chlor may be ideal. This comes up when people have new gunite/shotcrete/plaster or tile pools that are curing, and, as they cure they drive up pH. Being new water, they also need CYA. THEN Tri-Chlor is good to use.
There's a powder called Di-Chlor that's very similar to Tri-Chlor. It's not as acid but adds even more CYA than Tri-Chlor. Same rules apply.
Cal-Hypo, the third powder, adds calcium, which may or may not be a problem...if it gets too high it's a problem.
Best is Bleach/ Liquid Chlorine. No side effects to worry about!

What are your current water testing results? Depending on what they are, we can recommend what would be the best source of chlorine for your pool.
And just as a footnote to Carl's post, some trichlor tabs contain copper, so make sure to check your active ingredient list before you buy them, if that's what you decide to use. If it says "dual acting", or has copper in the ingredient list, don't buy them--copper is the culprit that turns hair and nails green. There are still some out there that do not contain copper. They may be a little more expensive, but not if you catch them on sale. Besides, in the long run the "cheap comes out expensive" because copper is a real PITA to deal with once it gets in your pool in levels high enough to start staining.
That being said, Please post your water testing results, as Watermom suggested, and we can help you go from there.

OK, I have a 25,000 gal gunite pool. Just at the tail end of opening. Water is clear after 6 days of 24/7 filter and at least 20 gal of bleach over that time to keep my CL levels up to clean up the green. Current reading are:
FC - 3.5
CC - .5
pH - 7.2
CYA - 0
ALK - 130
So I was assuming my next step was to get my CYA up. But I'm looking for proper direction at this time. (and exactly what product to purchase to do it) thanks
You could use trichlor, but the CYA rise will be slow, and your pH may tend to fall, which you don't need. I would just buy the stabilizer by itself--you can get it in the spa section at WalMart in 4 # jars. It's labeled "conditioner" or "balancer", I can't remember which--but look at the active ingredient--you're looking for cyanuric or isocyanuric acid. You can add it through the skimmer but not backwash for several days, or add it in a sock or old knee hi and hang it in front of the return.
If you do opt to use trichlor instead, go ahead and pick up a box of Borax too, and keep an eye on your pH.

If you have trichlor or dichlor, you can use it to get your CYA up; if you get the powder, use it to add Cl and the CYA will come up over time. quit using it once your CYA reaches 30-50, and use straight bleach after that for Cl...
if you don't have trichlor/dichlor already, I would get stabilizer/CYA and add direct, and just use bleach for Cl...
Remember what someone said about new gunite- drives pH up! so you may need acid to keep it in check
and later, you'll want to keep your CH up to prevent the gunite from leaching into pool over time...
