I have found a really nice piece of limestone rock with a tunnel running through the centre which I would like to put into my 53g community tank.

I know that it will raise my ph. My ph is currently around 7.0. I would like to know if this will bother my black ghost knife fish (cant find the profile on them, its gone?). I have some gold and blue rams, clown loaches, yoyo loaches and an angelfish.

Will it bother them, I will only be adding one piece and I have had it soaking in a bucket for a couple of days.

Should I add it or not??? As much as I like it I wont add it if its detrimental to my fishies.

Thanks for your advice

Hi,
As the limestone leaches into the water your hardness
will increase and pH will increase. IF you never
changed the water, over a period of time it (pH) would
probably reach 8.x. But, you do regular water changes
and I would say that the change in pH would be hardly
noticeable, perhaps shifting only a point or two between
changes.
I don't think it would affect your knife fish as you
would not let the water go for that long. Enjoy the
piece of rock in your tank.

Thanks for the reply Frank, yep I do weekly water changes of 50% so I guess i'm good to go.
