Any sand, really. However, I advise not to use sand collected from outside.

Thank you. I'm using pavior sand. Is this ok in a tank with a tetra easy crystal filter box 600. With a easy filter biological grid and filter cartridge. The reason why I ask I because in losing my fish. I've recently just had to change the tank as the other cracked. I couldn't get another tank until the next day. I had to think quick. I transferred the water, fish sand into a very large tub. I adapted the tub so that the filter and heater could be used. Got the new tank transferred water, sand and fish once set up. I didn't leave the tank for two weeks like advised. I'm losing my fish slowly. Is this stress related? Have I made them sick? Water readings are good. My fish that have died looked as tho they had white spot. So water treated. I currently have a neon tetra tying to swim but floats to the top. I've lost 3 Harlequin tetra they looked as tho they were bleeding in side. Any idea what's happening?

My fish look like they a going furry/fuzzy. If that helps.

Sorry to hear you're having issues with your tank.
1. Water parameters will always help, if you could provide those. That will give others insight into possible issues with your tank.
2. Pictures will also help. Sometimes what we say isn't always helpful in describing what we see, especially in stressful times. Your fuzzy to you could look slime covered to me. It's very helpful for us to see what you see.
3. Google "Cotton Wool Disease" s and see if that looks like what you/'re seeing on your fish.

I think your sand is the culprit. You changed the fish to a temporary holding cell and transfer the media and they seemed fine.

When you scaped your new tank you added the paver sand which I’m assuming you’ve never used.

Sand should be 100% silica or quartz and some paver sand may have chemicals that could have leached into the system thus killing your fish. Paver sand reacts to water and hardens over time. It’s used to secure bricks and stones for landscaping. To harden a little chemicals are added.

At this point I think your best to pull the sand out and start over.
