Does anyone know of a product aside from your usual "PH UP" from the hydro shop to raise ph? Hopefully something I can find in a corner store or something since most stores or closed at this hour, and I needs to adjust asap.
I use potassium hydroxide and if it works with my rez I add potassium silicate also. You could check out and aquarium store or if the big boxes are open you might try this.

I just googled it while looking for a pH buffer.I have no clue if it is worth your time.

the problem with pH up products is that they are full of salts that come out when in contact with acids, so i would avoid them on soil, or any other medium where salts tend to build up.
a cheap option would be to get some sodium hydroxide from the hardware store, they sell it as crystals in tubs for unblocking drains, or sometimes as a concentrated (about 35-40%) solution. you will need to dilute this to about 5% so its easier to use and less likely to add too much to your res. a teaspoon of crystals in 100 ml of water would be about right, then add this a few mills at a time till your pH is ok. one tub will last years.
