I use combo Hanna 98129. I keep the electrode in storage solution. I use combo 1 time per week to control pH and conductivity in my 4 tanks. Sometimes only 1 time per month. My electrode is good calibrated, my tap water has pH 7,75 and 680 us of conductivity, after RO and resins, my water has pH 7 and 0 us…
I’ve change water this morning on my tanks, I’ll mesure the pH tomorrow.
No new breed for my phoenicurus because they eat a little of brine shrimp. I’ve bought new Moinas from interaquaristik because mines are dead but not sent yet.
