Water Temperature, CO2 and Fertilizer

[Crispino Ramos]

I live in Arizona and I keep the air thermostat at 79F to save on the electric bill. Does the water temperature at 76 to 79 Fahrenheit affect CO2 and fertilizer in the water column, plant metabolism and algae?

Hi,

Higher temps do require more c02 and the rate it diffuses is also somewhat dependent on temp..

I think 76-79 is not as much diff as if you went up to say 81-82 but that is just my opinion.

I am pretty sure Tom answered this question recently and I will see if I can find his reponse to back me up

Brighter light = shorter photo-periods?

I believe post 15 is what Gerryd was referring to. This concerns me as well, as my lighting mixed with room temperature during the day easily carries my tank temperature to the low 80's.

My home is at 82F, no issues, had things go up to 90F for a time before AC........did more water changes, higher currents, more CO2.

Things grow faster at higher temps.
