all 4 pool return ports are plugged

hi folks:
i have a combination spa and pool setup--the spa has a channel into the pool and both run off the same pump/d.e.filter: there are 2 return lines. 1 line feeds the spa and one line feeds the pool--i think; the pool has 4 return ports, 2 on each side--they blow a little air but thats it. i used a 1/2" socket & extension on the spa fittings and easily removed and cleaned them but this wont work on the pool fixtures--any ideas on getting these out? its a big, old pool (14' x 62') and the ports are about a 12" under water. any experience you could share would be much appreciated and thanks/ craig

Anybody have any advice for Craig??
