Finally nitrates are 0
 

about a month ago i was at about 10ppm.

i adjusted the flow rate in my remote refugium. added more cheato. and adjusted the lights to stay on 20 hours a day. and now nitrates are finally at 0

phosphates started at .15 ppm and just measured at .09 with a hanna checker. so hopefully those will go to 0 as well


180 gallon display. 40 gallon sump and 30 gallon refugium with relatively slow flow.

cheato and cyano grow like crazy under 6500k lights.

no signs of cyano anywhere else in the tank or sump
