Tabs are usually trichlor and, like granular CYA, are slow to dissolve.

Dichlor is usually granular and dissolves quickly, 1lb of pure dichlor will raise your pool's FC by about 6.5 and CYA by about 6. If you use it for daily chlorination, three or four pounds will get your CYA in range. Accept nothing less than 99% dichlor (55% available chlorine) There's lots of junk on the market some of which adds copper.
