RO H20 + Cal Mag Plus = Unstable pH

[fulltilt]

Oh, I like riddles. .................................................. .................................................. .................................................. . Tell us about your air pump lines and stones please.

Humidity in your area has a high PH ?

Hello & thank you for your willingness to help me troubleshoot here...

air pump lines are clear plastic from walmart (have successfully used these before)

two types of stones... 4 from walmart w/ blue plastic bases with airstones set in the top (again have used these w/ success before) and then 2 additional airstones from petco. They are solid stone and black in color.

Does the rise in pH seem out of the ordinary given the circumstances?

thanks

Here's the setup... 20 gallon tote with 6 airstones for a bubbling DWC for seedlings. Inside the 20 gallon tote there is currently 15 gallons RO H20 w/ 75 mL of Cal Mag Plus (5 mL per gallon Cal Mag Plus). There is nothing else in this reservoir. Air temps are around 68 degrees farenheit and water temps are between 63 - 68 degrees farenheit. Rating: 5
