Who Gives A Fish Forums

Purigen's the move, like Finny said. Slap it in a media bag and toss it in your canister. Clears up haze in like 12 hours. Also, check if your filter's impeller's clogged, that'll cut flow and cause gunk to settle.

I've seen this before. It could be stress from recent tank changes. Did you add new fish or move decor around? Also, what's your lighting schedule? Too much light can stress them out. Mine chill better with dimmer lights.


For real, lights matter. I run mine 6 hours max. You got plants? Too many ...

Yo, sounds sketchy. My boy had the same thing last month. I cut the beef heart for a bit, stuck to pellets, and it cleared up. Maybe too much rich food messes with their guts. How old's your discus?

Considering a change of heart, thinking of closing my saltwater tank and going back to keeping discus.

There's so much conflicting info online about keeping discus in a Juwel Rio 180 aquarium - 101L x 42d x 50H.

What's a safe number for this tank?

I'd be using a Fluval 307 external filter.
