Ways to lower the ph in my tank?

I have a species only tank with a pair of kribensis in a 29 gallon tank.
I know from researching their needs that they prefer 6.8 to 7.6 ph.
Our water here is pretty hard, usually 7.8 out of the tap.
I have sand as my substrate.
I have two HOB's on the tank, but unfortunately, not receptive of adding something
like peat moss; at least I don't think so.
I know I can use chemicals to lower the ph, but I would prefer to do it a little more
natural, if possible.
Any suggestions would be welcome and thanks gang!

driftwood will also lower ph some but i would use peat pellets you could also use additives that will lower the ph, i use baking powder to raise my ph.

I would put some peat in a net stocking and put that in the HOB´s media box.

i believe there are some water conditioners out there that neutralize ph so you could always use that when doing water changes

Can you buy peat pellets at pet stores?
Thanks for the help!

foster and smith sell pellets or sheets i have never used these when i was keeping discus i just used peat it will tint the water but if you want to keep fish that need a lower ph you do what you have to do.

Mark, the only thing I use to lower the ph in my SA tanks is pieces of wood. You know how much I hate to play with chemicals and I works perfect for me. I even have my discus breeding. However, some peat in the filter like the Swede suggests is not a bad idea either.

Ok, I really hate messing with chemicals as well.
I have a large piece of driftwood in the tank now.
I will add some peat and see what happens.
Has anybody here ever kept Kribensis?
I used to keep them 20 years ago and they bred constantly.
But I've been out of the SA/CA hobby so long that I've forgotten
too much!
Thanks for the help everyone!

Peat Moss worked well for me. You can buy a huge bag at a Home Depot or Lowes.

Well, the piece of driftwood that I put in the tank has really helped my pH levels.
The water is now a little brown in color from the wood.
The kribs are doing well too!

Remember unless these are wild caught.
They probably have never seen a PH as low as recommended.

Most are in the low 7's

Just a thought.

Yeah, their pH range is wide; 6.8 to 7.8
Mine out of the tap is 7.8
I'm shooting for 7.2 to 7.6
I picked up another larger male to go with my large female
and things are beginning to look good for a future spawn.
I know kribs are easy to keep and not much of a challenge to some,
but I love the colors and I love the parenting skills these little fish possess.
