I do not use Glut either.........that alone can keep things clean, ADA does not use glut. This suggest that too much light and not enough CO2, rather than ferts was the issue.
You're right more light gets more algae. We still can keep the tank algae clean with many stuff including a tons of amano shrimps etc. So we're choosing this way sometimes to see some plant in much better shape. And we're succcessfull in that of course.
But at some point i recognized that the same tank with same light, same filtration, same CO2 injection get's algae on the decor with EI. So i can fault the light because of that, of course still this light is very far from the ones you see in the nature. So the nutrients gets more than it's needed in my reading with this much of light. I have dosed ADA ferts (which we all know is weaker contain less stuff then our EI mixes), but i did not get algae on decor.
I know you say "do use less light", but that HC carpet will not be the same with low light for sure.
Stauro in your tank not require high light so you're right not using more there.
I am not saying EI is bad or cause algae. EI gives us very healthy plants of course (we're using that in many of our tanks). This works wonderful in many conditions. It is just an experiment that same system cause different things with more nutrients and probably less nutrient sucker plants. Luckily we're using different kinds so we can experiment this in person.
I have to add that we're using the full PS, Amazonia stuff for soil.
Before i got shot because of the ADA promo from the science guys I have to add that it's not the brand, it is the experiment of the weaker fert vs the rich fert in the same system with a specific plant. Probably HC is not a nutrient sucker and that's all the explanation (need more CO2 than nutrients for this plant). But still an interesting stuff that you can see algae on rocks with one and no algae with the other.
