I've heard some folks say that adding activated carbon can help with cloudiness. Anyone tried that? I'm thinking of giving it a shot in my 40-gallon breeder. Also, what's your temp at? Discus like it warm, and if it's too low, that can stress them and make the water look off.

Activated carbon can help, but it's a temporary fix. You gotta address the root cause, like overfeeding or poor filtration. And yeah, temp's crucial. I keep mine at 84°F, and my discus are thriving.

Yo, don't sleep on water changes. I do 30% daily in my breeding tanks, and the water's always clear. It's a hassle, but discus are worth it. Also, what's your stocking like? Too many fish can overload the bio filter and cause cloudiness. Maybe consider rehoming a few if you're packed in there.

I've had success with adding more live plants. They help absorb nitrates and keep the water clean. I've got Amazon swords, anubias, and java fern in my 60-gallon, and the water's crystal clear. Also, how's your substrate? If it's too fine, it can get stirred up easily and cloud the water.
