No problem brother… when you initially mix a new res… give it a few hrs then re adjust the ph again. After that it should be stable. If not let me know ans we can tweak things to get it perfect@Aqua Man
Changed the nutes Saturday. Once the nutrients were mixed in, pH 7.0.
It took 60 milliliters of phosphoric acid to lower the pH to 5.5.
30 hours later PH was 6.6. added another 15 ml phosphoric acid at 11:00 p.m. on Sunday night.
So far Monday 6:00 a.m. and 6:00 p.m. pH 6.2... dare I to hope that it has stabilized?
Thank you for your help.
