ceg4048, Thank you again that is what I needed to know. I am just starting out with planted aquariums. I have been reading up on planted tanks and one thing that I have always seen on other forums are people saying that dosing too much ferts will cause algae. I was afraid of adding too much. If that is not the case then I will follow your instructions. If dosing full EI will not casue algae to grow then it makes sense to me to dose the full amount them scale back as you suggested. I never wanted to starve my plants I just did not want to feed the algae.

One question will adding ferts with no CO2 do any harm? Just wondering....

The lighting fixture I have does have reflectors and it's accually a 2x65W unit. I just never used the second ballast. I thought that it would have been too much light.
