Hello all, back for an update. I rented a 4in trash pump and let it rock for 15 hours while i could be there to babysit the gas tank. That drew it down another 12inches and decreased the surface area a large amount since i have a big shallow area.. I also ordered a pallet of hydrated lime and it came in today. I am planning to go out this week and ending all inhabitants. My plan is to put a trash can in the boat and two small pumps, one to pump in and one out of the can to create the slurry with.

Any other suggestions or food for thought would be great. Thank you all!
