Who Gives A Fish Forums

Thanks for the input, everyone. Sounds like it's possible but risky. I'll try a 50/50 RO mix and monitor their behavior. Appreciate the specifics on setups!

Tank is 75 gallons, planted with driftwood, sand substrate, and a Fluval FX4. Temp stays at 84°F. Anyone have ...

Thanks for the help, everyone. I really appreciate the advice. It seems like surface agitation is pretty flexible as long as there's some movement, so I'll probably experiment with my wavemaker to find the right balance for my discus. I've also taken ...

I'm currently planning for discus and I'd love some input.

For surface agitation and gas exchange, do you guys prefer airstones or wavemakers? Is one better suited for discus than the other?
