Which type of lens should I buy for my Cannon a520 digital camera?

[Yuri De Lima]

Since my a520 can't take good macro pictures with the lens that it has I'm trying to see if I can buy a lens kit to get good shots.

I did I search on Ebay and these are the 2 options I have:

10x Macro Lens Kit for Canon PowerShot A540 A520 A510
(which is four lens total)

10x HD Macro Lens for Canon PowerShot A540 A520 A95 A80
(comes with only one 10X lens)

Does anybody have any experience with these lens, which one would be better to take closer up shots of fish and corals?
