Hello I’m am struggling with ph I have a fish room I have 12 tanks running off a sump with a overflow straight into my sink waste pipe the system is around 1300 litres I have RO and HMA water trickling in 24 hours a day giving me my water change I have got the TDS steady at around 70 ppm but the PH is around 7.6 and will not come down?
Any help would be much appreciated.
