Here is my problem in my 75 gallon tank. I have CO2 injection in my tank controlled by a pinpoint pH controller, but the controller never turns on. The pH never fluctuates (pH stays around 6.9); therefore never turning on CO2 injection. My KH is 4-5. By using the chart I should have perfect CO2 levels, but that cant be true…can it??
I spend 7 hours in the same room that my tank is in and I know the CO2 never turns on. Water changes are done by RO water on an irregular basis. Typically after water changes I wait a day to check KH and GH. My KH never needs adjustments, GH typically does. I adjust my GH with Seachems Equilibrium.
Other tank spects:
pH is always around 6.9
pH prob is Calibrated once a month
Substrate is Eco Complete
Filter is Eheim 2226, hasn’t been cleaned in 3 months
Fish: 7 Angelfish, 10 neons, 1 oto.
Plants; Hair grass and Anubias
Ferts: I follow Seachems chart, but I do not add Excel
Driftwood
Tank history: This tank has been up and running for 4 years. I had it run for about 3 years. I then emptied it and it sat empty for 8 months. When it was empty of water the substrate and driftwood sat in the tank. The driftwood totally dried out and the substrate stayed slightly moist.
My big question is why does my pH stay stable at 6.9. What is causing my pH to stay around 6.9?
My plants are starting to suffer
Thoughts??
Thanks in advance.
