Fantastic, <"karst springs"> always look great.The limestone pool is 10 metres deep
I just took another trip to Emerald pool in Krabi, I think this is Vesicularia sp. (?) and might be “Krabi moss” or “Christmas moss” form since its from limestone water?I have krabi moss, it’s meant to be from there, it loves my water so it makes sense if where it’s from is rock!
