Hi,
My PH seems to high and I would like to monitoring the PH more frequently. I found digital PH meter pen seems very cost effective and a lot easier than the API testing kits I currently use.

Do you think the digital PH meter pen is good enough?

My tank:
  • 100 gallon.
  • 7 fishes. (clowns, tanks, gobies and dragonet)
  • BTA, some beginner corals, one clam, a coco worm,
  • Those common invertebrates, etc.

Thanks for any advice
