I'v been having troubles with my Ph level and somebody suggested it was my Geodes because they were made up of mostly Limestone

What is your PH?

As long as your PH is stable, you don't need to worry!

My ph is high and I was told it could have to do with my drift wood I added also something about ( tannins )

low, perfect, and high is no use to us. we need figure.
pH from 6 to 8 is acceptable as long as it is stable....
meaning doesn't fluctuate that much on a day to day basis.
if the limestone is not treated nor cured, it will make your
tank acidic.

my ph scale goes up to 7.6 and it is that or a little more (how do you cure rocks)

7.6 is not bad...just don't let the nitrates go beyond 40ppm
for too long. if ever did reach that point, large water change is
a must without disturbing the filtering system.

limestone isn't a good rock for your aquarium and will affect the PH. I would remove it and find something better.

what do you meen by not disturbing the filter system

yes that was my reply about limestone...im not sure if your geodes are limestone but this rock does raise pH....mine is also 7.6 wich is just fine...dont worry..also driftwood lowers pH. i have a texas holey rock and it only slightly raised my pH.
7.6 is o.k.
