best discus tank water softener

[Slybird]

For precise control, get a GH/KH test kit and a remineralizer. I use Seachem Equilibrium for my 180g. Mix RO with tap to hit GH 6, KH 3. Discus are in pairs now, showing breeding behavior. Key is consistency—no sudden changes.

Just use distilled water from the store. My 29g's been running on it for months. Discus are small, but growing. Cheap and easy, no filters to mess with.

Mixing tap with RO's the safest bet. My 55g's at GH 7, KH 4. Fish are healthy, no stress. Weekly 25% changes, and I drip acclimate new water over an hour. No crashes, no drama.

Thanks for all the tips! Gonna start with RO mixing and see how they respond. Appreciate the help.
