The reason we dose vodka is to lower no3 and po4 di ba besides to stretch our budget for saltmix users hehe my question is... is it possible to recycle the dirty water (water siphoned during water change) by dosing vodka in it? for example, i made a 5 gal wc, then transfer the water to a pail, run it through a fine net to catch detritus, then treat the water with vodka to lower no3 and po4, then when those elements were undetectable, we use it for the next wc. possible po ba?
