Do NOT use EI with new Aquasoil. Years ago when I knew less than today I did this and it was an absolute algae farm. The whole idea of Aquasoil, especially when new, is that it contains plenty of nutrients so only minimal water supplementation (mainly of potassium and traces) is needed.
Aquasoil leaches a lot of ammonia/ammonium to help the plants acclimate and start growing vigorously and provide a source to kickstart the nitrifying bacteria. However too high levels are also bad for plant and microbial health so very frequent water changes are required, up to daily for the first week. This discusses proper Aquasoil usage as well as other aspects of ADA methodology and starting a new tank. Using this method I cycled my new AS tank in just 3 weeks, with essentially no algae (mainly some minor diatoms).
In my opinion the results are well worth the effort.
