is liquid carbon safe for fish?

[flourman]

I've been using liquid carbon in my planted tank for a few weeks now, but I'm worried about my tetras. Has anyone had issues with fish health after dosing? My tank is 20 gallons, with a sponge filter and LED lighting.

Liquid carbon is generally safe if dosed correctly. I've used it in my 40-gallon with Cardinals and Rams for years without issues. Key is to start with half the recommended dose and observe. What's your current dosing routine?

I agree with floraborn. My betta tank has been fine with liquid carbon, but I only use a quarter dose. Maybe tetras are more sensitive?

Yep, gotta take it slow. I messed up once by overdosing, and my shrimp didn't like it. Now I stick to half doses, and everything's chill.

My tank's got a mix of guppies and neons, and I've been dosing liquid carbon daily for months. No problems so far, but I keep an eye on them. Maybe check your water params just in case?

I dunno, man. Liquid carbon seems sketchy to me. My corys started acting weird after I started using it. Could be coincidence, but I cut it out and they perked up.

Corys are sensitive, so that makes sense. Maybe try excel instead? It's gentler.

Thanks for the advice, everyone. I'll try cutting the dose in half and monitor my tetras closely. Appreciate the help!

Good call. Let us know how it goes. Also, make sure your tank's well-aerated—liquid carbon can reduce oxygen levels.

Yeah, aeration's key. I run an air stone at night just to be safe. Better to overdo it than risk your fish gasping.
