I’ve been battling a high PO4 for a long time in my 180 FWLR. Mushrooms and elephant ears only. Using a refugium and a gfo reactor with no results. Water changes siphoning off green algae gravel with no success. Mushroom corals have shrunk and barely open. I’ve recently used LaCl3 to lower the phosphate and accidentally achieved zero. Success. But…
That stated, I’m amazingly seeing regrowth of green algae on the gravel. Even with zero PO4. And teeny tiny opening of mushrooms.
My thoughts are turning to my LED’s. First generation hydras from AI.
My thoughts in believing this are my other reef tank with similar high PO4 but lit by hydra 52’s. No algae growth and mushrooms fully open.
Is it possible my LEDs are no longer providing the proper kelvin temp and spectrum? I look at my tank and think back to fluorescents and a red shift.
Are my first gen AI Hydras not providing proper lighting anymore? I’ve searched hydras in this regard but have found no info.
All my other parameters are in proper amounts.
Is appreciate your thoughts and advice.
