PH..should i worry?

[jonny toe tags]

When i first started my tank, my ph was 7.2.....then it held at 7.0 for a couple months.
I tested tonight and it is at 6.7.
Should i worry?
What can i do to bring it back up 'naturally'?

Here's more info:
Amonia: 0ppm
Nitrite:0ppm
Nitrate: 10ppm
ph: 6.7

It doesnt sound like anything to get excited about for sure. There are several possible causes but first what do you have in your tank ornaments, wood etc and what is your KH and GH if you have it. Just asking to see if there is an immediate answer that we can provide or if it is just something like a change in tap water parameters. Speaking of tap water what are the readings on your tap water? Anyway like i said certainly not anything major at this point but it would be nice to find out why. keep us posted

I have 1 piece of driftwood, one flat rock and a variety of live plants.
The GH is roughly 6-7 deg (100-120ppm)

I will put money on the drift wood it will naturally lower your PH by bringing down the hardness. Its not something to woory about just keep it in mind and if things get too low then post again and perhaps we can find some other cause. The main thing is that if you dont have to mess with the water chemistry then dont and if the occupants are doing fine then you dont have to be concerned. HTH
