Help in Collasium

Help!!!
I've only found one of the tablets, and don't know where to go to get the other two.
I've found one mermaid who says "She'll win a prize" if she finds them, and that she is close to a "secret". Obviously to secret for me also.
I think I've found a total of 4 of the Glow crystals, but I don't have enough to use in all the keyholes at one time.
How do I get the 4 cells open with the crabs in them?
I had to take a couple of days off, I was so discouraged.
Please help -

THere should be levers on the wall near the cages to open them up.

If you have completed an area you opened with a glowstone completely, you can take the glowstone back. If you found 4 of them you should have more than enough!

If that mermaid looking for a secret is still around, whack her once and watch what happens!

Xignal76 threads usually contain links to his cool walkthroughs if you get stumped to the point of needing one, but Collasium is pretty easy once you figure out that rotating room!

All right... Thanks for the pointers... But I still need one more.
I got the second tablet, and I think I have all of this place mapped. The only places (That I know of) I couldn't get to was the room with the tunnels with running water coming through them.
If someone could just tell me the basic area where I could get the third tablet I'd at least know where to pinpoint my search.

There is a room with debris on the stairs leading up to a path that goes both right and left down two short corridors.
You need two glowstones here to open each door and keep them open! Beyond the doors are two small rooms with buttons or levers on the back wall above small pools of water.
Turning the levers in each room will open up an alcove back at the head of the stairway in between rooms.
