Ph reduction

Go outside

Shells/coral take it the other way and also increase hardness. Hardwood leaves ike the ones leftover from last autumn work really well, have oak leaves gathered from street-side in almost all my tanks - just go where the dogs haven't and/or rinse them before immersion. Understand that letting water sit with aeration will also do a bit as it speeds formation of carbonic acid.

Ro water is not an option lol, but the leaves area good idea thanks avatars. About how much does it drop the ph? My ph is 7.3 and I want to get it to at least 6.6?

Depends on water change frequency/amount and number/type/period of immersion for leaves. I find that I can get pH down to around 6-6.5 in a10 gallon with a handful of oak leaves if I don't change the water for a month+, but for precision one has to test unless you're using known buffers/additives where the formulas have all been worked out with respect to required amounts per volume.

Why do you want it so low? What kind of fish are you keeping?

Well I have a planted 20gallon will a piece of driftwood in it and the ph is 6.5 in there, and like I said my ph straight from the tap is 7.3. The driftwood does a good job in that tank, even if I do a water change the ph will go up to 6.9 and drop back down.

That's not really low but I'm breeding apistos and they love the ph in the mid to high 6 range. The reason I know this is I have a pair of triple reds in my 20gallon that I got 3days ago and the ph started at 7.3, I put in A piece of driftwood the same day I got the pair and on the third day they bred for me and the ph was at 6.4.
