PH too low? help.

[Saluqui]

Hi All,

I have a new 20g reef tank. Just about 1 month old. Cycled and have a couple small fish and a cleanup crew. PH gets to about 7.8/7.9 during the day, and dips to 7.1/7.2 just before lights on. Is this acceptable? My alk is 8.6 ....Thanks!

Is the room well ventilated, meaning is there a fresh air source

Not very. It's Winter here in CO, and the tank is in my bedroom. I wonder..I have a Reefglass skimmer that runs on an air pump. Does this matter?

pH generally drops at night, but if you are in the room at night (I would assume) your exhaling is adding CO2 to the room, which may push it even lower.

Options may include opening a window or have the skimmer intake outside air from an airline. However, if other parameters are fine and livestock is fine, I would just monitor and keep an eye on it. Your tank is young so as it matures you may see it level off higher.

Here is some more helpful information link on vent the skimmer or setting up a reactor. There is a link to the setting up a reactor in the small article @120reefkeeper does a good job on setting up a co2 scrubber
