Overall length including the barbed fitting is 9 3/4". The width including the barbed fitting at the widest part is 3 3/4" . Depth including the airline connector is 2". Without fittings the dimensions are 8 1/2", 2 3/4", & 1 1/2".
Baseline Tap CO2
PH = 7.4
has been running between 15ppm and 25ppm with the old diffuser, a RedSea CO2
Reactor 200. Most of the readings are closer to 15ppm. I'll try to get some current readings later, since I didn't get around to testing or installing the new diffuser yet.
I did the leak check this morning and both reactors passed with flying colors. Yeah!
I also tested both tanks for CO2
levels this morning about 1 hour before the lights are scheduled to come on. That means that these are probably pretty close to the highest that the CO2
will be all day.
Baseline 2.5 CO2
PH = 7.0
Baseline 5 CO2
PH = 7.2
Neither of the passive diffusers have been working as they are supposed to lately, but the results on the 5 Gallon definately explain why I've been having problems with BBA lately. The results for the 2.5 Gallon were right where I expected both tanks to be running.
