peat decreasing my pH??

Hey all, I have a pH I want to bring down (7.6 currently for past couple weeks) Is using peat (I bought Fluval Peat Granular but have not added it in yet) a good idea? I heard it's pretty beneficial for planted tanks.
Thanks!

So whats the question? What is it that you'd like to know exactly?

It won't hurt anything but if your adding CO2, it'll screw up the ph/kh/co2 relationship.

If you're asking if you need to bring down your pH for your plants, then it depends on what plants you have.

Some people use a thin layer of peat in their substrate, I believe it aids in bacterial growth.

Adding peat to your filter will lower your pH, if you really need to, but it will turn your water yellow-brown and probably decrease light penetration.

Sorry about being unclear.

So will adding peat to the substrate lower pH as well and make the water yellow as well?

I was thinking of adding it to my filter....

What is better? Filter or substrate?

Thanks

Adding peat to the substrate is a better idea than putting it in the canister. It might still lower the ph a little but not as quickly. Add it as a first layer then cover it with substrate. I have a low tech 10G with peat in the bottom that grows plants remarkably well with only 20 watts of light and no CO2 and no fertilizing of any kind. Growth is slow but very healthy with no algae issues.

Some people prefer it in the canister so it is easily removed when it decays.

Plus the peat is supposed to reduce your KH.

m.lemay But how does it mess up the co2 chart for calculating levels?

The ph/kh relationship for co2 is based on using only co2 to lower ph. By adding something like peat to your tank, it will lower the ph without adding extra co2 throwing the charts out of whack.
