PH Levels

Zylski · 08/25/2009, 09:45 AM

So can corals and fish live and thrive and grow under 7.5 PH? That is currently what my new milwaukee controller is reading my tank at. Everything is growing at super high speed and is colored up really well. Is my PH truely at 7.5?

I would check the calibration on your pH meter. If you're experiencing fast coral growth that seems suspicious, as it becomes very difficult for corals to lay down aragonite at such low pH levels.

Ive calibrated it to 4 on back and 7 in front twice. That doesnt seem to be the problem.

I would suggest using 10.0 fluid. while 7.5 is possible. IME over the years. 9 times out of 10 it is due to testing error.

Ok do you calabraite to ten on front or back and if front do you use 7 on back then? And i did just do tests and heres what i got

Mag 1260-1290ppm
ALk 3 MEQ 8.4 DKH
Calcium 420
PH 7.7 with one test kit and 7.8 with another.
