I have had a low-grade but frustratingly persistent algae problem despite sequentially adding all of the usual suspects (very oversized skimmer, large refug, large GFO reactor, new bulbs, heterogeneous CUC, and Vodka dosing; was considering Bio-Pellets but experience seems to be anything but uniform and Vodka really did nothing useful for my tank). This algae has limited coralline growth on my LR (although I am frequently scraping it off the glass).
Despite a 5 stage RODI w/ a booster pump, I have been suspect of my water. At times, I have tested my fresh SW mix and have found measurable nitrates (0.2) despite only 001 TDS and new filters. As my large system requires 6G per day of RODI for evaporative losses, I think that low-grade nitrates in the water may be of particular issue for me. Am now thinking that I may need to filter water into larger intermediate tank and then use a 2nd RODI system (Spectrapure has one that will give 1:1 product).
Anyone in the SPS world using well water? Am I being too neurotic? Any other ideas?
TIA, Steve.
