This week I tested Ecological Labs Microbe-Lift 7.5 pH Buffer Stabilizer to determine if it would stabilize my pH at 7.5. It did not. My pond continues to fall below 7.5 at both morning and night. The goal is to keep my ph at 7.5 or above so that nitrifying bacteria can reduce my nitrites. This product may work in some ponds but not in mine.
I have 1600 gallons with 8 medium koi. Water changes 15-20% per week.
Added 2 lbs per instructions.
pH rose above 7.5 initially and has fallen as low as 7.2 1 week later.
This would be my normal pond behavior so buffering has no effect.
Only other chemical used was Chlorine remover when adding water from mains.
Only 1 filter cleaning performed during this time.
I would call this product a failure. If you have had luck with this product please let me know your particulars.
