Good morning,
So, I've hesitated to post this because I thought I could get this under control myself. However, I've got an algae problem. Specifically, cyano / red slime. The crazy part is, everything in the tank is as it should be. Phosphates, nitrates, nitrites .... all zero. PH 8.27, Alk 9.5, SG 1.026.
I have a 180gallon reef, with an 80 gallon sump w/ fuge, Reef Octo skimmer, and live rock in a separate sump (just for surface area). Total water volume through the system is about 250 gallons (Fish room is well away from the reef tank so I have a lot of volume tied up in plumbing). I also run (2) GAC reactors and (2) GFO reactors which return to the system through a 200 micron mechanical filtration system (so no dust in the tank). I have flow meters on the return lines, so I know I am pumping exactly 17.34 gallons p/m back to the tank ( 1040gph = 5.78x turn rate). From there I have 2x Tunze circulation pumps in-tank, each pushing about 2,100 GPH for a total circulation of 5,240gph (29.11x). The whole system is controlled by a vast network of Apex hardware.
The only place I can think I might be light, is on my cleaning crew... I don't have a ton of snails or crabs in the tank, but I do have a sand sifting sea star, some nessarious, and few crabs.
With regard to Livestock, I run a mixed LPS/SPS reef (LPS dominant). I have a foxface, (2) Chromis, (2) Antheas, 1 Longhorn Cow Infant, Tomato Clown, Juvenile hippo tang, small yellow tang, and a Kole tang.
Any advice is welcome advice. I need to get this straightened out. My phosphates had been high, so I really through adding the GFO would take care of this, but it's been a month now and no-dice.
