18 months is prime breeding age. If you go RO, grab a TDS meter to track hardness accurately. I aim for 150 ppm in my breeder. 75 gallon, dual sponge filters, daily 10% water changes during spawning. They're fussy but worth it.

Peat can work but it's messy and might tint your water. RO is cleaner but you'll need to remineralize. I use a mix of 75% RO and 25% tap in my 120 gallon, with Seachem Equilibrium to hit 4 dGH. My Discus spawn every 3 weeks now. What's your pH? They prefer it under 6.5 for breeding.


Yep, RO's ...

Fluval E300 is sketchy for Discus, IMO. Had one fail on me last year. Switched to a Cobalt Neo-Therm 200W, and it's been rock-solid. Also, check your tank placement—drafts mess with temps more than people realize.


Second the Neo-Therm. Mine's running 24/7 in a 90-gallon with zero issues. What's ...

I'm 0 for 2 on frogspawn now, no idea what's going on, just can't seem to keep them alive, had the same issue with hammers too.

Always great to see Dean's work featured on the Aquarium Coop's channel - he's just so down-to-earth and easy to like. His tank setup is really something special, the in-tank background and tiles create a beautiful environment for those stunning discus.
