How to safely lower ph in an aquarium
Hello the ph of my water is 8.0-8.2 and i was wondering what is a safe way to lower ph to around 6.8? Any suggestions or comments would be great thanks

Adding reverse osmosis water. It may not be readily available for most people though. I have it since my water cooler uses large 5 gallon jugs and they are filled with water treated by RO units.

yes i havge thought of that, but like you said it is not readily avaliable to evryone, and it is alot very expensive. thanks for the comment though

Well I believe you can buy RO water at your local grocery store. If not, bottled water IS distilled, so you could use that too.

is that very expensive?

No. It costs like 10 dollars for a large 5 gallon drum. Even less for smaller jugs (2 and 3 gallons are pretty popular) obviously.

Also, many bottled waters vary from oneanother. Some are hard, soft, more alkaline, acidic, etc... It depends really so maybe bottled water isn't the best option - unless you use your water test kit and find a brand which suits your tank best. :D

What size is you tank? Adding bogwood to the tank will help to lower the pH, but I'm not sure if it would lower it as much as you're looking for.

You know you could also just go to your LFS and buy some pH stabilizer. They have it from 6.5 to 8.2.
