Stability is better than perfect. If it swings that low you should be good.
How old is your tank?
What kind of top/lid/canopy do you have?
Keep in mind pH will swing, being higher during the lighting hours and lower during the dark hours. Try to take your readings the same time each day.

You don't want it to fluctuate any more than 2 or higher.
How old is your tank?

You don't want it lower. You want it between 8.0 and 8.4 roughly. A 0.2 swing in pH is fairly typically between morning and evening.

i have this stuff called "perfect ph" you simply open a package and pour it in your tank and in about 2 hours..it made my ph perfect and it has been perfect ever since. you could try that. its in a pink and yellow package

I tried the buffering thing but, for me, it got to be a pain. Mine was too low, so I adjusted my ph to make more surface ripple and it stays balanced out. That plexiglass is probably causing your pH to be lower. I used to have a lid but could not get my pH up, so I took off the hood and did the ph adjustment, and all is well. I know there are folks that use the pH buffereing stuff with great success, but I am not a big fan of adding things to my tank.....I kinda take the all natural approach.

Almost every single time I see PH mentioned in a thread, people say not to do a thing with it.

From what I've heard, KH and PH are related, and so long as your kH is stable, you can pretty much ignore pH. Trying to alter it could result in more trouble, hassle, and cost than the benefit of having it where you want would be worth.

So to repeat what others have said: Don't mess with it!

In other words: "Love the (ph) you're with!"

I wouldn't say that at all. It may be true with freshwater, but I don't do fw so I don't have a clue there.

Stable alkalinity is good, but it can be too high or too low. Just because your alkalinity is stable doesn't mean it's good. If you have a alkalinity between 8-12 dKh, then you should have stable pH... regardless of what the number is. While not accurate, you can think of alkalinity as a pH 'reserve'... more alkalinity will allow your pH to resist its normal tendency to drop.

But if your pH is below 7.8 or so (even if you alkalinity is stable), you might want to figure out why that is. If you're not seeing any ill effects, then it's probably better to just leave it alone. But there's an underlying reason why it's low, and if you CAN fix it, you probably should.
