I will get the names of the plants to help, getting an actual water test tonight. Of the 4 plants in the front of the tank 1st on left was added just yesterday. The 2nd and 4th are approx 3 weeks in tank. The 3rd one was cut from the 2 i bought together about 5/6 weeks ago. (that is the tall red stemmed plant) I cut tone of the red stemmed plants in half to see if i could get new plant about a week ago.
This tank has a fluvel plant and grow light . I just did a test strip. No Nitrate or Nitrite (do water changes evey week), GH is at the top of the range (at least 300) KH is medium (below 120) and the PH is 7.8 or so. The GH just seems really high but i have limited context to what the figures actually mean. Fertizlizer is from Aquarium Co OP
