Who Gives A Fish Forums

Thanks for the tips, everyone. Gonna test a batch in a bucket first and check the bag for silica. Appreciate the help!

Play sand can work, but you gotta be careful with the silica content. Some brands have additives or coatings that mess with water params. What's the brand? I've used Quikrete before with no issues, but it took forever to rinse.


It's the generic stuff from Home Depot. No brand name, just labeled ...

I just bought some play sand from the hardware store for my 20-gallon tank. It's the fine, light-colored kind. Anyone know if it's safe for my Corydoras and Neon Tetras? I rinsed it a bunch, but wanna double-check before I dump it in.

Keep looking for any leftover food and remove it, that's still a source of ammonia. Also, give your filters a good cleaning, the water's still passing through them and it's possible that's where the issue is.

My tank's pretty low maintenance, only additives I use are food, sea salt, Calcium for my corals, and Bicarb to keep the alk stable.

Geez, I think your tank's got some issues, dude. I had an ammonia spike in my 12-gallon tank, and it only reached 0.25 ppm - nothing died. The nitrates did jump to 80 ppm, but they're back down to 10 ppm now. Your fish might just be hiding, stressed and scared, so it's not coming out. I've had fish ...

Poor Nemo... I'm really hoping she'll be okay. My mom thinks she's been doing this weird swimming thing since we first brought her home, but I don't know, I just don't think that's true. Hopefully, it's not as serious as it sounds. She's been doing this for about four months now and she's still ...

I've been observing my Percula clown for a couple of days now, and it's been acting pretty strange. I'll enter the room and catch it leaning to one side, only to see it flip upside down, then right itself again. The symptoms seem to match those of Swim Bladder Disease – loss of balance and abnormal ...

I've had two unexplained coral deaths recently, so it's possible this is related. The affected coral isn't dying yet, but it's killing patches of zooanthella. If you look at the second pic, there's a bigger dead spot where I scraped off the puffs - I'm still not sure what to call it. Not all those ...
