Eco complete is pretty inert, so I doubt it will effect micros that much. I reccommend you get dry ferts as they are cheaper in the long run. They also offer more flexibility. Say your plants use a lot more N than P. You will be wasting or even overdosing on P, though overdosing is not the root cause of algae issues.

Might want to check your KH and GH of the water. 7.6 is barely "high". You might need to cut with RO if the GH/KH are really high.

TL;DR. Lights -> CO2 -> Ferts. These are the 3 main players in planted tanks. EI rules out ferts by introducing nonlimiting supply of nutrients. That way plants can grow at max rate as driven by light and CO2. If you haven't already read, excess nutrients does not cause algae.
Forgot to mention my lighting, 20 watts to my 10 gallon tank, I've been getting mixed signals on the necessity of CO2. I'll look into DIY setups. How can I check my KH or GH? I did put some pH down in it last night and lowered it to around 7.2 and now is back up to 7.6-7.8 which makes me think the GH is high (or is it low?). Would I be good if I got the micro/macro mix from Would that fulfill all the ferts I'll need?

Thanks for the reply
