As Seffie says, nothing wrong with using sea water if it is pollutant free. For example, I live in the North West, nearst coast is Morcambe Bay, I would not trust that source to be honest but if you have been told about a good source, that is fair enough. I would still test it for nitrates and phosphates though as fertilisers can get into the via run off.
I would probably want to filter the water myself through either UV, diatomaceous earth filter or both before using it.
If it is left stagnant with no movement for more than a day, plankton can start to die which will increase ammonia levels and cause bacterial blooms.
You can store the water in the dark for a few weeks before using then decant or syphon the clear top water off, and discard the detritus.
If you are not having any problems, you probably will not want to do anything like that, if you do start to get any problems, they are options for you to look at.
Yes you are right, collect when the tide is coming in.
