Thanks for the welcome! And I think my flourish is the plain? Just says flourish-a comprehensive supplement to the planted aquarium. I don't have excel but thought I might need some. My other swords are doing ok in miracle grow but do have some spots so I will probably do tabs. As for light: I keep all my tanks on for 10hours. This is a new bulb for me and I've been considering it moderate light. The reason I went with them is because on my bowl I have a 15 watt of the same brand and plants grow well and algae isn't *too* bad. It's the equivalent of two 75watt incandescent bulbs. So does that make my moderate light assessment correct? Is that too high for low tech? I'm already having balance problems in my two 5gals that's giving me bloom and I really don't want to deal with it in this tank. So I'm just left guessing about any light/nutrient weak spots I may have.
