I was looking for some large black lava rock 5-10 inches but no rock yards or landscaping supply has black lava rock other than the small 2-3 inch ones. The aquarium safe rocks i did find wanted like 5$ a lb or 20-30 apiece.
Now I'm simply willing to use any aquarium safe rock and paint it black. Maybe if i call around I can find large red lava rock and simply paint it...I've heard of tons of people using krylon paint for plastic on pvc
in their aquariums but was wondering if that would work on rocks or if there is any other paints that would be better for rocks. I've also read ANY non toxic paint as long as it wasn't oil based would be fine. Doesn't seem to be much info online in painting aquarium rocks
Anyone have any ideas?
Edit Note: Any Suggestions on different types of black rocks I wouldn't have to paint or even nonblack rocks would be great too if they're cheap or reasonable like granite or something. Thanks for your time.
