    Ok- i think youre asking how to make your ph level higher? add some crushed coral substrate, or texas holeyrock or any limestoney type of rock (it will make your ph level higher) also you could add crushed coral to the bottom of your filter...
    i would NOT use chemicals that supposedly make ph levels higher.. i dont believe chemicals really "fix" the problem and are not natural or healthy for the fish-- and only stress them out.
    i have crushed coral as gravel in both of my cichlid tanks.. it shouldnt bother some of the plants ,but others will have to go.. some of the less hardy plants cannot handle high ph levels.. stick with anubias, java moss and fern and maybe amazon swords.. they seem to do well..

    Be careful the ph swings can be harmful. It is best to raise ph slowly .2 a day is what I was told.

    Honestly, even with the low PH, if they are having babies. DO NOT MESS WITH THEM

    stability is more important than numbers. and anything tank raised is prob fine in the lower PH Simply leave it alone.
    and as opposed to crushed coral (SHARP and pointy) I would recomend any other calcium baced product. such as
    Calcium arginate
    other than in the filter I would prob not recomend crushed coarl. although many to get away with it.

    Still IMHO if they are breeding in 6.4 leave them be.
