Wanted to as on your opinion on what kind of algae is this?
Before that short story:
1 year old stable tank had 0 nitrates and 0.03 po4, all parameters stable, changed my sand bed and added about 30lbs of dry rock which were in a ro/di water for a month to leech po4.
a while a go cyano started to show up, and got rid of it about 2 weeks ago using chemiclean.
after increased my nitrates to 4ppm using NaNo3, lps corals loved it and seems that sps aswell.
so now i have some brown algae for about two weeks - they do not disappear at night and they do not have snot or bubbles.
So could it be that:
1- the new sand and dry rock is leeching silica and i am having a diatom bloom?
2- i am having brown cyano?
3- dinos?
Would appreciate any ideas what am i dealing with and how to deal with them?
and po4 now is 0.04 and nitrates at 3ppm
