  1. Can anyone help me to identify a mineral/rock which melted in my aquarium? It was a fist sized white rock with grey veins in it. Thought it was quartzite. Vinegar does not make it fizz. It melted down to a few thin chips (pictured below). It only took three months for this to happen. It made the water smell like sulfur and caused a white growth on the substrate that was soft and floated easily when disturbed. (Pictured below). I thought it was a fungus and had to aggressively siphon it and affected substrate out to get rid of it. It did not kill any fish but did affect water quality—because the fish were less active and worked their gills more rapidly. It did kill plants by destroying their roots. Any ideas what the mineral or rock was? Any suggestions as to how I can test remaining chips? I have to admit that I licked it to see if I could taste salt 😝(but it doesn’t have a taste). Just wanting to learn.
  2. I'm new to keeping shrimp but know they have some special mineral requirements for molting and staying healthy. I've seen some put crushed coral in their tanks for calcium, but I haven't done so. I don't know my exact hardness or TDS but I suspect they are mid-range (have seen calcium/lime build-up on tanks allowed to evaporate). I do have the Hikari shrimp cuisine but don't feed it everyday since they're sufficient biofilm. My question is, how much calcium do they need? Are there other good sources than crushed coral? What about pulverized egg shells? What other minerals are important for shrimp health/molting? One of my RCS is turning a cloudy-white. I'm not sure if this is due to molting recently/preparing to molt or if they're not getting enough needed minerals. I know one molted very soon after being introduced to my tank because I saw the exoskeleton, but since then, I added them (there was 3 total) to a larger tank until I re-scaped their dedicated 5 gal shrimp tank. Because they're in a 33 gal with lots of plants and rocks, I hadn't seen them much but now this one seems to be out and about much more. Not the best pics but gives you an idea of what I'm talking about. Thoughts? Should I just add the crushed coral? Anything else?
  3. I live in a mineral rich area. Lots of abandoned mines within 100 miles from my front door. Mostly iron and copper, but also silver, gold and even a few diamond prospects. I get most of my hard scape from the poor rock piles (the rock that doesn't contain ore.) Are there any mines I should stay clear of? Which minerals are bad for fish?
