Been to dozens of pool forums and this one seems the most organized and useful, with intelligent queries and replies, so I'm gonna give it a shot to help solve my problem since I've exhausted all my efforts with the experience I have. Thanks in advance!

First, the details;
POOL: 18' x 48" Intex, round
CAPACITY: 7,700 gallons
PUMP: Intex Krystal Clear 635T

What I've been using;
HTH 6-way test kit

KIK muriatic acid, 31.45% strength
HTH chlorinated granules (for quick n easy chlorine level bumps)
HTH super 3" chlorinating tablets (for ongoing maintenance)
HTH super shock 'n swim
Arm & Hammer clear balance 3" tablets (conditioning)
HTH super extend algae guard (this stuff is great!)
Leslies Pool ulta bright enhancer (clarifier)

The Problem..
Ive read countless posts about this problem and have considered every possible cause. I know its NOT equipment, algae, bather load, rain, pipes, metal, Ph, hardness, chlorine, wild animals, bikinis, aliens or freaks of nature.
I do know it has to do with Alkalinity.. which is where I'm stuck. After getting Ph within the 7.2-7.8 range, my AK level was still 260!! So, on to the acid I went.
72 oz. later my Ph has dropped to 7.0 (expected) but AK still at 170 and most frustrating, VERY little improvement to cloudiness. (you can see the bottom of the pool if you stare long enough, which is better than -0- visibility before, but a long way from sparkling clear.)
I have a feeling it has something to do with my Cyanuric acid level which has been -0- the whole time, while I'm clueless as how to change.

What do I do next without further dropping Ph or creating other problems? Help!
(below are my readings and steps I took)

DATE/TIME CH. PH. AK. HD. CA. (chlorine, Ph, alkalinity, hardness, cyanuric)

5/26, 733pm. 3.0. 8.0. 210. 200. 0.0

6/13, 800am. (same as 6pm readings above)
* drained 1/3 of pool. Skimmed and vacuumed, refilled.
1200pm. 3.0. 7.5. 260 ?! 230. 0.0
* just as cloudy, add 8oz acid, 5oz clarifier

* cloudy, 16oz acid. Pump always on.
1200am. 4.0. 7.0. 170
* cloudy. No action. Pump always on.

6/16, 1200pm. 3.0. 7.0 170. 200. 0.0
* 1st signs of.progress!! Water is SLIGHTLY less cloudy. Cyanuric still 0.0.
* Adding 16 oz more acid., 3oz clarifier
300pm. 3.0. 7.0. 160. 200. 0.0
* no change to SLIGHTLY improved cloudiness..

So, there you have it. AK is.going.down, albeit slowly. However, ph is dropping and the cloudiness has barely changed.

PLEASE HELP, how do I remove the cloudiness and keep everything else in balance?!
Thanks!
