I've been dealing with this since the start of the tank. The ph always hovers in the 7.8-7.9 range during the day and down to 7.6 at night. When i can open the windows all is great and well.
I've ran a line from the skimmer to the outside world and it has made little effect.
My tank is very lightly stocked imho. A 4-5inch yellow fiji leather, 6 heads of candy cane. few inches of gsp. A few small kenya tree's, a small clam, small green tipped toadstool, 7 recordia's, 4-5inch rock covered in zoas, and now the gbta.
salinity 1.026
calcium is 420
alk is 10
mag is 1440
I run t5 sups without reflectors im sure they ad some par just not much from 3pm until 10:30pm
I run the mh from 4 until 10pm
the reefugium bulb runs from 10pm until 7 am.
What can i do? The tank always looks alot better when the ph is 8.0 or higher when i can open the windows.
I do weekly 10g water changes with reef crystals. total water id estimate at 40-45 gallons. Tank is a 40g br with 35-40#'s of lr and the 20g sump is partitioned into three sections. skimmer,return, reefugium with cheato.
I'm trying kalk right now with a 20oz bottle with a drip every 12 seconds. and no effect yet with half of the bottle gone. I dont want to dose much since my levels are where i want them except ph. I might have to change to reg ol instant ocean so i can add alot of kalk to keep my levels constant.
any idea's
