Hi everyone,
Well, I have a problem going on with my PH level. Tank had been holding a good ph level of 8.4, then last week I broke the electrode on ph meter. I've replaced electrode and recalibrated the meter. My first read with new electrode was PH7.9, temp 77.3F, 1.023sg, 3.2meq/l alk, cal was 500mg/l and magnesium was low at 1160. I added some magnesium to tank and 24 hours later tested again, tank then tested at PH7.9, temp 77.1, 1.023sg, 2.6-2.8 meq/l ALK, CAL at 500mg/l and Mag up to 1200.
Last night I added balanced two part cal/alk supplement hoping to bring my alk and ph up. Tested today and my PH has fallen to 7.6. Temp at 77.1, 1.023sg, 3.0meq/l ALK and CAL 450-500mg/l. Why would PH and CAL fall after addition of 2 part dosing. I should mention that Ammonia, Nitrites and Nitrates are all at 0ppm and have been for a couple of weeks. I've also been doing 10% wk water changes.
Am going to dose a bit heavier and see what effect it has on CAL and PH.
Any ideas are welcome - need some guidance to get PH back up!
