Sorry to speak english, "ich spreche nicht deutsh"

You could see the presentation of my sps tank on the presentation section.
Some of my sps are perfeckt( acro tortuosa, gomezi, turaki) : it's the species with smooth skin and little polype.
Some are pale : acro millepora, acro hoeksemai, hyacinthus.
I'm beginning Sangoikai basis protocole since 5 days, with the hope to have a better tank.
Some questions please :
1. is normal to have more green algae on the glass please ? is it the effect of sangokai trace element ?
2. how the nitrate and phosphate must progress please ?: down or up please ?
3. I 'm reading the A-Z sangokai pdf, but it is for me unclear (with translation) what level of parameters are advise ; No3, PO4,Kh.
4. I'm reducing the production of chaetomorphae in my refugium to have more nutrient : good or bad idea ?
5. I don't understant if a little refugium is advise, if zeolith and GFO si advise, or just a pure berlin method with just a skimmer ?
6. I hesitate to remove my evergrow 5012B led, and come back to my 8*54W ATI sunpower...
7. I will do an ICP test : can I add some additional and individual trace element please (Iode, etc.), or just add the Basis product ?
thanks for your big help,
Best regards from Paris, France
