What Causes PH To Be Too High?

Hey all,

I tested my PH today about 4.5 hours after lights-on, and it was about ~8.6. I Just did 18% water change yesterday.

Most have problems maintaining PH, but what causes it to be too high?

Ammonia = 0ppm
Nitrates = 0ppm
Nitrites = 0ppm
dKH = 8
PH = ~8.6



90 Gallon Drilled Glass Tank w/ Corner Overflow: 492w (2x 150w 14,000K MH, 2x 96w Actinic CF) Coralife Aqualight Pro | Custom 34x15x15 Sump/Refugium | SWC Skimmer | Coralife Turbo-Twist 6x UV Sterilizer | Maxi-Jet Power Head w/Sure Flow Upgrade Kit | 120lbs of Live Rock | 100lbs of Live Sand

Actually, Anthony Calfo wrote an article in his magazine "C....The Journal" that pretty much states we keep the ph too low in our tanks and that 8.6 is more the ideal. I would think if yours is staying there with no problems, I would leave it alone.

I agree, if it stays stable, you should be ok.
Age is relative, you are only as old as you act....of course, this works in reverse....

Questions loved, heeded advice greatly appreciated!

I have to agree with Lisa as I keep mine at 8.4. But as the others stated Stability is the key.
