Ohhh... "flora max" is a light! I thought you meant "floramax" as in the substrate that is exactly like Eco Complete.
Yes... lighting is an important component to growing plants. By all means, upgrade.. but in terms of your co2
generator... 7 bubbles a minute is really REALLY low! You need like 1 bps at least. A drop checker is a visual device you fill with a pH reagent solution and 4dkh. It reacts to the pH in the water to give you a visual estimate of how much actual co2
is being diffused into the water. For example, the drop checker will be blue if there's not enough co2
, green with just enough, and yellow when there's too much. I suspect with 7 bubbles per minute, you'll be in the dark blue. If you upgrade your lighting to the dual t5ho fixture, especially with good reflectors, you'll need to upgrade that co2
system or supplement your current system with Excel (or Glut).
