So nutrient levels in my tank have been fairly steady (around 10 NO3 0.1 PO4 based on salifert) but I had set up a slow acclimation ramp with my Kessil A360x a month back. A green film and hair algae bloom snuck up on me between routine cleanings and really took over the tank. Around this time I invested in the USB par meter from apogee and realized the tank was probably way over-lit and dialed the lights back to a more reasonable range. That combined with cleanings, mechanical filtration and skimming, brought the algae under control (it's no longer growing back quickly, coralline is steadily spreading on rockwork) but I'm concerned that nutrients might be a bit low in the tank. My euphyllia, stylos and goni extend much less now, but still somewhat and NO3 lies around 2-5 depending on how much I feed and PO4 are around 0.1 still. My question is whether I should hold steady until the algae cleans up and maybe the polyp extension will bounce back on its own as everything readjusts to lower light and recovers from having irritating stringy algae everywhere, or if there's anything other action I should take while the film algae and last bits of the hair algae die off / get eaten up by CUC?
