Peat water softening...

Question- I've read many places that peat filtration will soften water. But it also leaches yellow/brown (which I really hate).

So- if I do peat AND charcoal, will I get the softening effects without the discoloration?

Peat will lower the pH, not soften the water meaning lowering the gH & KH.

If you want soft water, you'll need RO or distilled water.

Actually, the tannic acid in peat WILL break down kH.

But I don't think there's a way to separate out the tannic acid from its color- so if you pull out the tannic acid with carbon, you'll be dramatically reducing its effectiveness.

So I agree, RO water is going to be your best bet if you don't want to deal with the coloration from tannic acid.

i love the way a little bit of tannin looks in the water. think it looks great, and more natural too.

one thing you could do is get a 5 gallon bucket of peat an pour boiling water on it and let it drain into other bukets. that will leach out the tannins into a seperate bucket and you could add the extract slowly till you get the color to a tolerable level

what about the gh? TDS overall?

Try testing the peat in two 5g buckets: one with carbon and one without it. If the pH goes down in both, you're good. If only in the bucket without carbon, you'll have to lower the pH by some other means.

Thanks for the info guys... another question... what are thoughts on the softening pillows? *If they're recharged with KCl not NaCl?

What exactly is your goal in softening your water?

If you're trying to breed some species of specialized fish, you need to focus on maintaining water parameter stability. It's extremely difficult to achieve and maintain any target water parameters when using peat or any other type of additives to water or filter. If you want to maintain stability, it's best to start off with RO water and then reconstitute it to add back the trace that plants and livestock need.

Read the details carefully, those pillows regen in salt brine. I don't think they will work as the resin is different between those conditioners.
