Pepperdine, huh? I live a few miles away in Ventura County and noticed the
same thing with a vermiculite/soil 29g and local water when I started my
tank. I used the black adobe in my back yard for the soil - but i've never
tested it for pH. I have since started DIY CO2 and the tank is 4 months old
but I have not checked pH recently. However the fish are happy and the
plants are now requiring regular thinning.
