Just used an online ammonia calculator, and with the current ph of 5.6 and total (NH4/NH3) ammonia concentration of .5 mg/l (or .5 ppm…they’re the same), the NH3 concentration is only 1.4 * 10^-4 ppm NH3, toxic ammonia…guess that’s definitely not the problem…The total ammonia would need to be extremely high before that became a problem (some 34 times the current value would be required before it exceeds the EU standard for NH3 in drinking water…about .005 ppm).
