You can put a resin in the filter that makes the pH drop. I think that's the easiest. Should be available at your LFS.

What else do you do to your water? Adds? Substrate? Frequency of water changes? pH is the wagging tail, not the dog.
The water in my aging barrels also have high pH and it is DI. The aquarium is 200gallon with a 75 gallon refuge with large red volcanic rock for the bio filtration. My filter is made from 2-5gallon buckets. I also have 3 large pieces of driftwood. I have a gravel bottom with I clean 2 times weekly and put in new aged DI water. Ive never used any chemicals.
I have nothing. I can't imagine how an aquarium filled only with deionized water could sustain life of any kind. Something has to be coming from somewhere, otherwise your pH with pure deionized would be much lower - below 7.0 for sure - depending on how much CO2 you have dissolved. Maybe someone more knowledgeable than I will respond.
The tap water and DI water is 7.4 when I do water changes. I change 55 gallons 2X/week. The gravel looks like it comes from the coast because there are alot of clam shells. The fish are doing well regardless of the high pH. But the plants are suffering. The tank is natural, not CO2 injected. Any ideas??

Take a sample of your gravel wash it and dry it and place it on a paper towel and place a few drops of white distiller vinegar. If it fizzes then you have alkaline substrate.
Which is great for ciclids and salt water setup.

I placed vinegar in the three substrates, pumice, gravel, and red volcanic rock and no bubbles on any of the 3. I dont understand why the red volcanic rock does not bring down the pH. My meter is calabrated and is 7.1 in 7.1 test solution. I have a medium fish load, I have 1 male Microgeophagus ramirezi boliviana and 5 females which have hatched 4 batches of fry. None of the fish die, most of which are from the amazon, 3 Britlenose ancetrus, 6 Otosinclus, 12 Corydoras, 5 Botia macracatha, 34 Cardinal tetra. I have several Echinodorus which are slowly dying. Its low light , natural light in the morning from greenhouse setting. My fishroom is a converted greenhouse.Thanks Jimmy

Yes but how are you replenishing the traces, Kent ro right? Seachen alk buffer with acid buffer?
If you are putting straight di water into tank it will take on whatever is in the tank. Di water is like a sponge. You should be buffering it prior to putting it into the tank.
