Will a peat filter soften water?

[willy]

I've been reading about peat filters and their effects on water hardness. Does anyone have experience using them to soften water in a planted tank? My tap water is pretty hard, around 10 dGH, and I'm trying to get it down to 6 for my Tetras.

Peat filters can definitely soften water, but they're not the most consistent method. They release tannins and organic acids that lower pH and GH over time. I've used them in a 20-gallon with driftwood, and it took about two weeks to see a noticeable drop. Just be ready for the water to turn tea-colored.

Yep, peat works, but it's kinda messy. If you're cool with the brown water vibe, go for it. I'd pair it with some Indian Almond Leaves for extra softening. My Betta tank loves it, but my Corys? Not so much. They're picky about changes.

Exactly. Consistency is the issue. If you need stable params, consider an RO system instead. Peat's great for biotope tanks though, especially if you're aiming for a Blackwater setup.

Aye, peat's legit for softening, but it's slow. I chucked some in a media bag in my HOB filter, and it took a month to drop my GH from 8 to 5. Also, test your water weekly, 'cause it can swing if you're not careful.

I've had success with peat in my shrimp tank. It softened the water gradually, which is safer for sensitive species. Just avoid overdoing it—start with a small amount and monitor. My Caridinas are thriving now, but it took patience.

Yeah, Corys can be drama queens. Peat's a solid choice if you're not in a hurry. Just don't expect overnight results, and maybe skip it if you've got fish that hate tannins.

Thanks for the input, everyone. I'll start with a small amount of peat and keep an eye on the params. My Tetras should appreciate the softer water, and I don't mind the tannins.

Good call. Just remember to recharge or replace the peat every few months. It loses effectiveness over time, and you don't want your GH bouncing back up suddenly.

Peat's cheap and works, but it's a hassle. I switched to RO water mixed with tap to get my params dialed in. Way less guesswork, but yeah, it's pricier upfront.
