Here's a quick update on using Sodium Hydroxide. I've only been using it for 2 days but the results look promising in helping raise my PH. I've upped my dosing by 20 ml per day as well to 155 ml. dKH is stable at 8.1 and I may let it rise to about 8.5. I think I can safely do this being that I have elevated nutrients.Trying something new to me.
My PH has never been ideal no matter if windows are open or bringing in outside air through the skimmer (that I currently do). I dose BRS 2 part + part C and currently dosing 135 ml Soda Ash and Calcium to keep my ALK at 8+ and CAL in the 400+ range. As you can see from the chart, my PH doesn't even break 8 at peak and dips below 7.8 nights. I was adding the soda ash from 12:30 AM to 9 AM.
As of tonight starting at 9:00 PM I'm replacing the Soda Ash with Sodium Hydroxide and continue dosing the same amounts. The mixture is 283g per gallon of Sodium Hydroxide that should be the equivalent of my Soda Ash mixture. The difference is the Sodium Hydroxide is supposed to boost the PH by about .2. If it does that, I will be a happy camper. I'm going to add the Sodium Hydroxide from 9 PM to 9AM.
Hope this helps without crashing the tank!
