Tide doesn't matter. What matters is chum! Make sure you have it. I've used tuna and mayonaise when I've ran out of the real thing and it worked great. They won't stick around wihtout chum.
don't put bleeders in the box , save them for bait or chum later on , also if possable rig up a sea water pump system , if that is not pratical at least put a drain tube in and periodicly pour in a bucket of fresh sea water good luck
