Reef safe plastic glue

[Chin_Lee]

i would use caution trying to waterproof these plastic tubs. you may be able to seal the hole without any water inside the tubs but when you add water, i find the bottoms of these tubs seems to warp as it molds to the weight of the water inside the tub. They were not really made to hold water but they do. However you may find that as the bottoms warp under the weight of the water, your watertight marine goop seal may not be so watertight after all which means you may have 50g on your floor if the seal breaks .......... when you are not around.
