Hi guys, its my first post. Im from Chile, sry for my english.
My tank is 130g + 20g of sump, 5 months old, and is an ULNS SPS dominant tank.
Lightining is 4 hydra 52hd with 100% blue and 70% white, red and green (13.500K).
My parameters are Ca 400 Kh 7.3 Mg 1380 PO4 0.0 (salifert), NO3 (aquaforest).
I add bacteria (aquaforest) daily, and have a reactor with phosphate minus, carbon and zeos.
Until 1 week ago the tank was wonderfull, sps growing fast and colorfull, but one day I had cyano and green filamentosus algae.
Like 2 weeks ago I feed with 2 shrimps and 2 clamps a copperband that finally diez, but I think that its the cause of the algae.
I check parameters yesterday and I have NO3 0 and po4 0 (Like always).
I dont know how to do it now. I will remove it manually dialy, turn off white reds and green from lamps and reduce the day 2 hours.
My doubt is about NO3, I need to raise them now or maintain it?
Skimmer: its works 12hrs daily, now I need to turn it off or use it all the day?
Feeding: the same or more?
Adding bacteria: stop it or continue?
Thanks u guys, and sry for my english
I add some pictures of my tank before cyano
