They really took off for only 7 days. A little dark but no burning. I've added a feeding at 5am. Maybe the blueish leaf color is potassium def=more feed. IMO.
Feed at 7pm for 3 min and 5am for 1 min. See how that goes. Not concerned either way. Switched to floramax to reduce white slime developers in my reservior..
Thanks, I used the Active Aqua Adjustable Flow Submersible/Inline Pump 800 GPH. I don't use any of the flow regulators from the bubbler. Wide open..back at the tank I put a small 90 deg elbow at the top of the to allow air into the line after it turns off. Stops it from siphoning..
