When your lights are on the organisms in your tank are preforming photosynthesis and converting co2 into oxygen.. At night the lights are off and and photosynthesis is no long occurring..
What ph should reef tank be
A generally accepted range for PH in a reef tank is: 7.6-8.4 However the ideal PH would be 8.0-8.3 That being said many have highly successful reef tanks with a PH less than 8.
What causes low PH in a saltwater aquarium?
-Excess CO2 in your home is the most common cause.
– people and pets breathing in the house
– CO2 reactors
-Carbon dosing
My PH is low.. How can i raise it?
– Open a window to allow fresh air into your home
– Increase surface agitation by pointing power-heads towards the surface to promote gas exchange
– Run an air intake line for your skimmer or airpump outside to draw in fresh air
– Raising your Alkalinity level can also raise your PH
– Install a small PC fan into your cannopy to allow fresh air into the tank
– Leave part of your sumps cabinet open to allow more gas excahnge
– Use a wooden air-stone at night (
Micro bubble scrubbing) which I run at night.
– Co2 scrubbing media on your Skimmer intake
– Run a
refugium on a reverse light cycle
– If your using a CO2 Reactor – try adding a second chamber or add a drip cup to let the effluent off gas.
