Hi Guys, Am wondering whether 7.8 is ok . There are heaps of articles stating that the sweet spot is 8.0 - 8.2 for sps. Some mentioned more about how stable/swings it gets during the day. I'm using calcium reactor and maintaining the PH readings at 6.6. I have aquatronica 3 dosing pumps that includes alk but dose in the morning only. should it be in staggered consistent dose during the day? Any dosing sifus do advise. My readings day is at 7.8 and at night 7.83 (swings at .03 avg) . Sometimes i get alerts in the morning my ph goes as low as 7.75 My other readings checked recently are alk 9dkh calcium 430 mg - 1280 redox - 444mv nitrite/nitrate/amm 0 phos - 0.25 (still battling for 0) Thank you for advises!
