Hello again. Just finished my first week in the group. Some of you may remember I had questions about why my pH has gone up. Scape includes Sakrete play sand and gravel, cedar driftwood, lava rock, and I believe the rock holding the wood down is river jack stone. Im using under gravel filtration, trying out the slow moving plenum method spoke of by Kevin Novak. Even have my air pump working on/off every 10sec. Tds of tap water is 20ppm. pH is 6.0. After a week tds is around 90ppm, pH is 7.5 and as of today it seems the tanks are getting a tad cloudy. Seems quick to be a bacteria bloom. Just tested kh and gh and I'm posting a pic of it all. Loving this journey. Knowledge is wealth. Thank you for your help. kh around 40. Gh around around 30. Please bare with me remembering to take photos in the correct orientation.
