Hello reefers

KH Director update and top-down coral photography

When I installed the GHL KH Director I posted some photos and not much more... so let's start the 6months review

The measures have been rock solid, very accurate with my Hanna that I cross check sometimes... (0.03dKh-0.15dKh variations from the Hanna) so not much "error" maybe the KHD is even more precise than the Hanna hummm

P4 + KH Director is also controlling my KH automatically for more than 2months keeping it very stable like you can observe on the graph below



And now some top-down coral photography


































piece.
