Question HELP PH Stabality

Here is the deal, I have 30 gallon with 3 jewels and a Convict. I have two pieces of driftwood one really big and one small that believe is the cause of my pH to decrease. My tap waters pH is about 7.2 after letting it set over night with a air stone. My tanks h is about 6.5 and 6.7 with the aid of API proper pH 7.0. If i were to stop use the proper pH 7 my tanks pH would drop below 6.4 even with 25% weekly water changes.

I want to stop using water buffers, i have a bag of hermit crab sand ingredients read (calcium carbonate and magnesium carbonate). If i were to put some in a bag and throw it in my filter(penguin 350) would that help to stabilize my pH???

PLease any info on any natural products that would help my tanks pH to stabilize!!

You are correct about DW lowering your pH due to tannins being leached into the water. The carbonate bag you have will raise pH. You could use Limestone, Marble to also increase pH. Eventually the DW will leach out the tannins and your pH will then reflect your tap water's pH. If your worried about trying to keep your tank at a specific pH for your fish, generally fish will adapt to various pH levels, as long as it's stable.

My tank pH is somewhere around 7.4-7.6 and my Barbs (prefer acidic water) are doing fine.

Ok, but if were to stop adding API proper pH 7 the pH would drop below 6.2.

For now the important thing is to keep your pH stable .. which is what your doing. For now the only thing to do, assuming it's the DW that's causing your pH drop, is to let them leach out tannins. Keep in mind DW can leach them for months.

Medium size gravel. You can see it on my aquarium photos.

I know that , i boiled both pieces of DW til pretty much the water was clear. DAYS!!!!!!!!!! What I' am trying to figure out is something NATURAL (like DW that lowers it) bring up the pH and maintain it at around 6.5-7. I don't care about raising it, I just want it stable above 6.5!!! The API Proper pH has phosphates and kinda makes my water hazy a little and my tank is semi planted.

I DON'T WANT ALGAE AND A HAZY TANK.
Help???

Gotcha... as i mentioned previously, limestone, marble or crushed corals will help.

I have a problem with my 10 gallon quarantine tank pH getting really low (so low the API test won't read it). I purchased a bag of the pH buffered cichlid sand and put some in a couple of filter media bags that had very fine mesh. Over the course of a couple of weeks, my tank pH moved from below 6.2 to stable at 7.0. The nice thing about using the mesh bags is I can remove the buffered sand at any time. The buffered sand wasn't cheap (about $23 at Petsmart) and I'll probably never use the entire bag!

There are other options that are cheaper, and already were mentioned by folks here. The point is, if you add something, make sure you can remove it from the tank or you may have too high a pH once your driftwood stops leaching!

Good call. that's why I'm not crazy about pH buffered sands ... because then you have to remove it ...ughh .. I can only imagine removing sand if the media bag rips. Crushed corals in media bags, along with limestone rocks you can get at home depot serve the same purpose, just easier to remove.
