I'm not using excel. I'm using a small ceramic diffuser with DIY CO2 and I'm seeing better growth than I was with the excel. If you're using the Red Sea nano filter you could also just run the CO2 line so it bubbles into the intake.
Mine is just sorta sitting there. The plants aren't doing anything. I don't think Excel is helping at all. I've been dosing a drop/day, plus a drop of Flourish 3x/week, and a drop of nitrogen 2x/week.
Mine isnt doing much, Im adding about 3 drops of excel a day and NPK 2 times a week. Anyone have a mix for diy CO2 on a 20 oz. bottle? Also are you guys running both light bulbs? I was running both then switched to 1 due to algae. What are your thoughts
Turn on the second light and add more excel, I add a full pipette to my cube every other day. Or. Get your DIY CO2 pumping. Try 3/4 cup of sugar, a teaspoon of baking soda, and an 1/8 teaspoon of yeast.
