Weekly Update – 12/28/2015 – Tank PH Keeps Dropping

By: Kevin | December 28, 2015

Since the last update:

  1. 20% water change – 50/50 Tap and RO water
  2. Vacuumed gravel
  3. Removed 3 large cups of tank water and replaced with RO. RO pH read > 7.5. Hoping this will bump up the pH naturally a little.

 

 

pH has dropped significantly ~6.0, Ammonia ~ 1.0-2.0, Nitrite ~0, Nitrate ~5.0-10.0

The darker blue the higher pH. A few weeks I ago I did a little pH test and the results were quit different. Tap water pH has always been much higher pH however my RO pH has jumped quit a bit.

This picture was taken 12/17/15, RO pH level is much lower (left). Tank water was also much lower than I’d like to see it.

Still not as clear as I’d like.
