First, what kind of algae? Brown, green hair, green bubble, red cyano
??? What's your feeding schedule? What's your daily light cycle?
I use the same salt as well, and you're not "very high" on those readings.... you're shooting for 450-480 calcium, 1400+ on your mag ( I run 470 & 1440). What does puzzle me, however, is your 7dKh. I usually run 8.7 on mine. 7 is not bad
, but definitely on the very low end.
Are you using API test kits for everything (marine master & reef master kits)?? If so, I would recommend eventually getting yourself much better kits, sooner rather than later. API is great for FW
, and getting your SW
set up & running, but just not sensitive enough for good
reefkeeping. Been there, made that mistake myself.. both API test kits are sitting in the cupboard, and am currently using Red Sea kits.
