I would do a 50% wc and remove as much of the algae as I could manually. Then I would reduce the amount of fertilization. I understand that many people have great success with EI, but I seemed to have thread algae problems until I reduced my dosing. I mixed up a solution that would give me a 1/2 dose of EI. I tried that for a few weeks, and then actually went down to a 1/4 dose of EI. I also used Excel in a syringe and squirted a daily dose on any algae that was left. For two weeks, you can use a double dose of Excel if necessary. After about a month of this routine, all algae disappeared, and plant growth remained good. I don't have to do the 50% wc's weekly using this routine (which I was doing when following EI) and do a 30% wc every 10 days, instead.

After you get your algae problems under control, you can experiment a bit with your dosing and see what level of fertilization works for you. You can easily increase the fertilization for two weeks and see how your plants react and if the algae comes back. If it does, then drop it a bit. It is all trial and error to see what works in your tank, with your water, fish load, lighting. etc.

I think getting your CO2 sorted out will also help.

Try not to get discouraged. With a little experimentation, I think everything will work out.

i agree with you, i have done many experiments to agree with you.
