    I use a mix of crushed coral and small gravel along with Boulder sandstone slabs as rocks and the pH hasn't ever wavered from 8.1... it's glorious!

    Ok my water perimeters are: ph 7.2-7.4, gh12, kh3. I use seachem malawi buffers and rift lake salt for every water change. how can I make this less expensive on the long run?

    coral or limestone rocks - something calcareous... will raise the hardness and the pH with it

    My tapper water has a ph of about 7.8 will adding limestone and cichlid mix substrate to the tank put my ph levels through the roof

    try it and test it...substrate and limestone take a while to "work" because it has to disolve into the water...
    I should use this space to promote the photo contest...but I can't think of anything clever...

    That's a quote from www.dictionary.com . Most of the Rift Valley cichlids would have high pH in their natural waters, over 8 for Malawi and closer to 9 for Tanganyika.

    Although I am concerned about water parameters, my experience is a little at variance with my fussing.

    Water comes out of the tap at 7.2 pH, 100 ppm KH. Over "African Cichlid" mix substrate, which includes crushed stone and freshwater shells, it gets up to 7.4 pH. Not really African cichlid water.

    However, my neo brevis bred in it, so often that I had to take their shells away! I think I got 200 fry altogether. My hap sp. 44 also bred in the 7.4, producing about 50 fry from two batches last spring. I think my borleyi would have produced a brood as well, but unfortunately I neglected to vent the pair at purchase time (oops).

    I think sensitivity to fixed PH levels is a species variable, and its a mistake to put your tanks on an additive diet unless the fish show you that your water sucks.

    My water from the tap runs around 8-8.2 for pH but contains alot of chlorine so I must treat it first......which brings me to my question....

    The 55gal- crushed coral in the filters and lots of holey rock, yet the ph doesn't seem to want to rise above 7.8, any suggestions, I would prefer it to be a tad higher?

    The 92gal- aragonite as a substrate, ph around 8.0, is this ok for tangs or should I aim a bit higher? I could always add some of the crushed coral to the filters and might make things perfect for this tank.......

    but what to do about the stubborn 55?

    Thanks everyone!!!

    when are you doing your testing for ph...right after a water change? chlorine removers sometimes drop the ph temporarily. how often do you do maintenance on your eheim--excess organic material can acidify your water.

    What is your hardness out of the tap<gH and Kh>?

    I had to remember KISS<keep it simple stupid.>

    Very simply the difference between your tanks is argonite vs coral/texas holey rock. Argonite disolves better so your 90 has a higher pH.

    You pH is hitting it's roof because your tank water is satuarated with ions already, hence why I asked what your hardness is out of the tap. In the cas of pure water coral will drive the pH as high as 8.6 and argonite as high as 9.2.
    (I think Zrock tested crushed marble and it hit above 10.0.)

    ex.
    take an ordinary glass of warm water and start adding salt and stirring at some point the salt will no long disolve because the water is saturated.

    If your fish are happy with the pH then you should be happy with it.

    I would define too much holey rock as no room for water. ;)
    The photocontest, like everything else is behind schedule. You get some links back today.

    I have pretty hard water straight from the tap, sorry don't have the exact numbers at the moment-- but I also add some cichlid salt during water changes. My fish seem to be just fine, so I guess I shouldn't worry. Awhile back I had my water tested at the lfs and they suggested I try to raise my ph a bit. I think I'll just keep using the crushed coral, I'm only using it in one filter now, maybe I'll put it in both.

    Thanks for all the advice, its much appreciated!!!
