Who Gives A Fish Forums

Sketchy to push past 30 ppm, imo. My dude's tank hit 50 once, and they got real lethargic. Backed it down to 20 with more plants, and they perked up. Java fern FTW.


Same here! Added a bunch of anubias and cranked the bubbles. Nitrates dropped, and the fish are way more active. Also, cut feeding ...

Yeah, stress is a big one. Also check your water changes. If you're slacking, the TDS might be creeping up. I do 50% changes twice a week with RO water, keeps 'em happy. What's your WC routine?


I agree with luxe! Water changes are key. My discus perked up when I switched to RO. How often do you ...

Agreed on the river rocks. They're usually safe, but testing is smart. My Oscars are picky, so I always double check everything before it goes in the tank.

First off, check their eyes. Cloudy or sunken eyes are a no-go. They should be bright and clear. Also, watch how they swim—healthy Discus are active but not frantic. If they're hiding in a corner or gasping at the surface, that's sketchy. My 75-gallon has driftwood and Java ferns, and I keep the ...

I'd play it safe and grab some white vinegar. It's cheap and reliable. Your Angelfish will thank you. My tank's got driftwood and slate, and I always test with white vinegar just to be sure.

I'm gonna grab my first Discus this weekend, but I'm kinda nervous about picking healthy ones. What should I look for at the store? My tank's a 55-gallon with sand substrate, planted with Amazon swords, and I've got a Fluval canister filter running. Water's at 84°F, pH 6.8, and I do 30% water ...

"Same with corals, right - a pretty coral by any other name would still thrive."

Thanks so much for all the helpful replies - I'm really grateful for this forum and the lovely community here. I've not had a chance to participate much yet, but every time I do, I'm blown away by how friendly and knowledgeable everyone is.

I really appreciate all the advice, especially about not ...

Hi everyone,

I'm in the process of setting up my new 180l tank, and I've decided to try my hand at a planted aquarium for the first time. I've laid down a layer of Prodibio AquaGrowth Soil, followed by a layer of Prodibio AquaShrimp Powder Soil as recommended. I've picked up a selection of plants ...

Re: It’s been 20 years!

Reading through this thread brought back memories, making me wonder if I was a part of this community back in the day when I first considered keeping discus, only to be deterred by our hard water. Fast forward to the present, I'm glad to have finally taken the plunge.

I dug ...
