Hi folks!
So, I'm about a week in running my sump. My return line is clear vinyl tubing and I noticed it is turning green. The DT water is clear. 1st chamber of the sump is filter socks and heater. 2nd chamber is UV sterilizer, protein skimmer, HOB refugium with chaeto and seachem de-nitrate, all turned off to try to raise the nitrates (@2.5ppm now). Last chamber is return pump and in/out lines to an external canister filter that has Matrix and Chemi-pure.
Any idea why the return line is green?
The display water is crystal clear.
Also, the skimmate in the protein skimmer is green as well, but was more brown when it was hanging on the back of the DT
