Thats what i used to do dose the recomended EI.
The only issue as above was the calcium content in the water with EI. I also find it's hard to get reds to show unless you absolutely beast the lights and then you need to run your Co2 high.
George has posted on YouTube a guide to Iwagumi which is worth a look. My ADA 60p is now Iwagumi. Just cycling the soil and then I can plant. Hopefully it will be less maintenance and I can concentrate on my Aquascaper.
