Hi:
REAL Noob here, so please bear with me....
Been noticing a bit of whitening on some corals- most notably some zoas. Color in general is a bit bleached, but some have white spots on their faces... or rings of white (depending on the zoa)...
Anyway, decided to get the test kits out. Ca is OK, maybe a bit high- 490-500. But the Alk worries me, too low. It has always been a bit low- 2.5 to 3 meq/L, but today it came in at 1.5.
pH is 8.1
I use Marin Tropic Pro, and (Always!) RO water. I just mixed in some Oceanic into my salt barrel, so I am probably getting a good mix of that in (just wanted to finish it out).
First, are these two problems related? Second, what can/should I do to raise alk w/o putting everything else out of balance?
Thanks!
Dave
