Sandstone, Limestone

[Blackcane]

Does Anyone else have problems finding limestone and sandstone? i'm swimming around for over an hour and only found like 4 or 5 stones

I usually find sandstone abundant in caves below 80m in kelp and grass zones, inside of geothermal vents and you can also harvest barnacles on adult reefbacks. Limestone is literally everywhere. Actually I usually scan limestone so I can tell at a glance between limestone and sandstone since one will always have the scan icon on it.

sandstone is usually in caves, search the kelp forest or indeed, the geothermal vents. There is a lot of limestone in the big coral tube cave in the safe shallows.
