My pH spikes again and I can not figure out why. My ammonia, nitrite, and nitrate levels are all 0 and I can not keep the pH low. My tap water pH is 7 and I use it in other tanks which are fine. The gravel is also the same used in another tank with low pH levels. Right now I only have two Cories in my tank as I am planning to keep discus whenever I can get the PH to about 6.5 steadily. The only thing I could think of is that I have a large piece od driftwood in my tank as well as a piece of marble. Would these cause the pH to spike?

It's odd nitrates are 0, usually there is at least some.

Definitely the marble. I'd take it out. The driftwood would lower the pH if it contained enough tannins.

Do you have any ornaments at all in the tank?
It might be a good idea to tell us of every thing that is in the tank including all the filtertration materials.

When you say spike does it come up occasionally or is it high all the time?

Does it alter much after a water change?

Near enough is not good enough, therefore good enough is not near enough, and only your best will do.

i have no ornaments in the tank. I only have the driftwood, a few fake plants and the marble. It is an eclipse filter. I lower the pH to 6.5 and it gradually climbs until its very high again.

I suggest you remove the marble then do several 50% water changes over several weeks.
Then get a full water parameter test done and see if there are any changes.
