I'd lower it slowly, like 1°F per day. Sudden drops freak 'em out. Your plants might struggle too if it's too warm. What kind of substrate are you using? Some hold heat weirdly.

Check your water hardness too. Soft water can make discus more prone to nipping. Mine stopped when I bumped up the GH a bit. What's your current hardness? Also, how often are you doing water changes?


That's a good point. I keep my GH around 6-8 dGH, and they've been fine. How's your KH ...

Thanks, everyone! Gonna try the drip method this time. My last betta seemed off for days, probably 'cause I skipped that step.

Just got a new betta and wanna make sure I'm doing this right. I've got a 5-gallon tank with a sponge filter, heater set to 78, and some live plants. How long should I float the bag before adding them in?

Thanks, all! Got an AI Prime light, Red Sea Coral Pro salt. I'll hold off till params stabilize.

Just set up a new 40-gallon tank and added live rock. How long should I wait before adding my first coral? I'm using a protein skimmer and keeping salinity at 1.025. Temp is steady at 78F.

That sounds like a good plan, Lexat. Just remember to keep the water clean and stable. Your Discus will thank you for it.

I love planted tanks for Discus! They look so much nicer and the fish seem happier. I've got a 55-gallon with Amazon swords, Java fern, and driftwood. My Discus are adults now, and they love hiding in the plants. Just be ready to trim and clean more often. I use a canister filter and do 30% water ...

I'm leaning towards moving them all out while I switch substrates, it seems like the safest option. Since I don't have a Petco nearby, I'm looking for a good alternative. You mentioned using Petco sand, but was that your top choice or just the most convenient option? There are so many brands out ...

Your setup looks amazing, bigtop. I think I'm leaning towards sand now. You mentioned you got the sand from Petco, but I only have PetSmart nearby and they don't carry it. I'll have to look into ordering online instead.

Moving on to my next question: when switching to a new substrate, especially to ...
