Getting the balance right is tricky, I have a twinstar nano and the nano bubbles it produces are great for accessing the flow as they get pushed around so easy, which makes accessing the flow so much easier. Getting the flow right in a CO2 injected tank is the key to getting the CO2 delivered to the plants. Trouble with constant flow is the dead spots are constant, which is way I was so happy with the Maxspect Gyres x2, as you can vary the flow on a schedule with them ramping up individually every few minutes so the dead spots keep moving around.
Its a case of trail and error and see what works IME
