Hoping someone can answer this for me. I only have a couple grows under my belt and am definitely still learning. I used Ph down to lower the Ph of my aerated reservior water from 8.4 to 6.5 before watering the other day. A few days later the Ph of the reservior was back up to 8.4. Is it safe to add more Ph down even though I just did it a few days prior? I leave the air stone on 24/7. Thanks!
