Hello,
I have 2 questions. I filter my tap water into a 5 gal bucket, lightly covered, and bubble aquarium bubbles through it. I'm wondering how long this plain water can sit and bubble before getting stale/growing things/needing to be replaced.
Here's the one I have problems with...
The other day I poured out 1 gal to feed. Added some cal mag and pH down. I just bought a fancy pH pen, it is calibrated. PHed to 5.8, threw an air stone into the 1 gal and left for 90 min to do something else.
When I get back and test, pH was back up to like 6.4 I don't remember. Markedly higher.
So do I pH until it's on the button and pour immediately? pH over several rounds and hours till it equalizes? pH the entire reservoir? Did the bubbles raise the pH, or just make it seem that way?
I am growing organic in coco, and I was worried at how much chemical pH down I kept having to add.
Thanks for your thoughts
