I have to disagree.
Each fish has a specific location and preferred PH. That is why most prefer specific tanks to community tanks. Mixing fish from all over can make it near impossible to replicate natural environments. It is true, and I'm not going to argue the fact, that most fish come from breeders and things like PH don't matter as much anymore, however if you ever plan to breed PH is VERY important. Some eggs will melt in different PH values, some fish will never mature properly in different PH values. They will live but not be productive.
Asia seems to have a pretty neutral PH between 6-7. South America tends to be 6 for plecos and SA cichlids. African cichlids tend to be higher in the 7-8 range. North American fish tend to be in the 6.5-7 range but have several areas of low PH and high PH but is generally limited to certain species found in remote areas. Blue Rams are especially prone to high PH, generally perishing in anything above 6.
To naturally lower PH add good pieces of driftwood. DW tends to keep the PH between 6-6.5. Another option if you have a canister filter would be to add peat to the media. peat tends to "blackwater" quickly leeching tannins into the water. To raise PH look for aragonite substrates and limestone rocks.
