Shamefully I haven't checked the alk
in the tank. I'll check that tonight. The tank is right next to an east facing window. It doesn't get direct sunlight (especially on rainy days like today) but it is viewable from dusk to dawn. The tank light is on from about 12pm to 8pm. Just enough so that he's still awake when I get home and settled in at the end of the day.
So even testing at 700 am (this morning) the sun has been up since 530 or so, I would guess. I also test at the end of the day 7pm. Last night when I tested it during the water change it was 8.0 (8.00-8.03
) and then this morning it was 8.00.
I was buffering it a little each day when I was dropping the salinity to keep the pH up. It will be interesting to see what the alk
My change water is always a little high in pH (between 8.4 and 8.5) so I pour the change water back in a little bit at a time over the course of the evening so it isn't happening fast.
How concerned should I be over the .2? I know ideally it would be zero, I'm just trying to figure out at which point I get drastic over it. I've seen people talk about readings of 10 (?!) My test kit only goes to 1!
I don't say thank you often enough, but I'm always thinking it
