10am when our boat arrived at Ulong channel, its was a strong incoming current.We follow the wall left shoulder and hooked in at the mouth of the channel and watch an action. A big school of bigeye scad chasing by greyreef shark,whitetip shark ,napoleon wrasse,jacks and tunas.After 30 minutes of watching, we unhooked and drift inside the channel, an amazing variety of corals all the way to exit point.

A deep dive in Sieas tunnel amaze our divers because of the beautiful structure of the tunnel its like entering to a big Cathedral with whitetip sharks sleeping at the sand bottom,big eye trevallies forming a big tornado,and colorful gobys hiding at the sandy bottom.

"That was a strong current" when we finish our dive. A big group of grey reef shark swimming against the current, napoleon wrasse,jacks,whitetipsharks,tunas chasing the big bate ball off big eyed scad.
