Ive dosed vodka for years with good results, nitrates 0-5ppm, i did get cyano but was removed with my gfo reactor. Im curious, has anyone switched to vinegar with same results or better? Im planning to dose vinegar thru a doser since vodka would evaporate to fast. Would the vinegar lower my alk too fast? I understand i would be dosing a lot more vinegar than vodka. 12.5 ml vodka daily. Heavy bioload 120 mixed reef, 440 cal, 7.7 alk, 1410 mag, 5 no3, 0.00 phos.
