Hi. Long story, but bladder got filled with water. Thankfully it isn't a one pump, just good old leading edge bladder. Thinking it will be easier and more thorough to remove it. Any particular tips?

Dont remove it unless you have to, open the deflate valve and lift both wingtips in the air pushing them flat together, the water should come out the valve.

A bit of seawater is not a concern, i've found sand from the pump more of an issue as it can put small cuts on the inside of the bladder weakening it.
so think of this more of a flush of the sand.

I found the best way was to elevate the wing tips, leaving the dumpvalve as low as possible. Just a matter of twisting the dumpvalve to face the ground and drain it out.
Pump it up after u drain what you can out and listen for any water swishing around, repeat process if need be.

Alright... Once upon a time there was a little kiteboarder . This little kiteboarder just loved to be on, above, but not in the water. This one time, just after band camp, the wind was positively lovely and the little kiteboarder couldn't wait to get on the water. At home, whilst packing his car for the short drive to his favourite spot, he remembered the new floating bridle lines that had arrived just a few days earlier. The little kiteboarder had purchased the replacement lines as the dodgy BCF cheaparse rope that he was currently using really should be replaced with quality dyneema line, he thought.
Whether it was because the little kiteboarder was such an optimist or because the wind was ordering the little kiteboarder to get in his car and drive, he said to himself, "self, the lines will be fine for one more session. Replace them when you get back, just go, now."
And with that, the little kiteboarder drove away, leaving the quality replacement lines on his workbench, and the cheaparse BCF line attached to the kite.
Now, if readers of this little tale were a cynical bunch, they would accuse the little kiteboarder of being lazy because the kite was his wife's kite and that if it was a kite he was intending to fly, he would most certainly have replaced the lines before launching his kite. Thankfully, the readers of this tale are not a cynical bunch
Now, the author of this little tale has work to do and really should leave the obvious conclusion to the imaginations of the readers. Surfice it to say, the little kiteboarder will in future always push the deflate valve back in before swimming back across the chanel after helping rescue said wife, and little kiteboarder will never again trust anything to BCF.

I once forgot to put the velcro strap over my dump valve and surely i had a big crash and popped the valve open, kite went from flying to sinking in about 3 seconds.
All i could do was float into shore making sure i didnt put too much stress on the canopy when each wave broke over it!

We all learn by our mistakes.

Just so you know some people advise you to flush out the bladder with freshwater if it got filled with salt water. Apparently once the saltwater dries the salt can crystallize and cause punctures (typically when folding up the kite).

Of course I've heard others poo-poo this as well so up to you.

Yeah but where are we kiting? The Dead Sea? Saltwater crystals around Australia should not be a concern. They powderise anyway when dry and dissolve in fresh or sea water. Even so, salt crystals are like less than 50 microns or far smaller than the thickness of your bladder wall. Chemistry 101 guys. Hehe

Not true, not true. After repairing hundreds and more like thousands of kites over the years I can tell you that salt water does form large crystals inside the leading edge and it will cause punctures.
Why does it form large crystals? Basic chemistry, water evaporates over time leaving a more and more concentrated salt solution, once a solution becomes "super saturated" with dissolved mineral salts, then abnormally large crystals can grow.

If you get salt water in the LE, put a few liters of fresh water in the LE, inflate LE carefully to a soft pressure rinse from end to end and then elevate the tips and open the dump valve, North owners open the inflate valve. One pump owners, leave the struts clipped off during this process.
After you have dumpeed the water inflate the LE again, leave for a coupe, of hours, any remaining water in the LE should have evaporated and will escape as vapour when you deflate the kite. If any water remains, repeat the inflate and wait process.

I stand corrected. Yes, multiple crystals over time can cause damage. However, why are you allowing water into the bladder in the first place?! Something wrong there.

Haha man. That's like asking people who damage their kites why they did it. I think it's kind of implied that it is unintentional.
