The local popular store, Aquarium Concept, is using this new CO2 system. Have anyone ever used it?

Freshwater Planted Aquariums: Red Sea Turbo CO2 Bio-System

I asked them about it and they showed me what they are using. This is the same thing as the one they shown me.

On the site, it said to have it hooked up to a timer to turn the system off at night to prevent PH drop.

Its basically DIY CO2 with a venturi diffusor. The venturi is like an airpump that forces the bubbles into the tank. I have one on my 55g (need to get another) and it works well. I didn't see a significant pH drop, so I don't think its helping that much, but I like to think it is.

There is a girl on another site I visit that has 2 hooked up on her 55g and she has about 4wpg and her tank looks great! And she doesn't have an algae problem. :)

The diffusor is the best part...IMO.

With CO2 systems like that, needs to be on all the time. Can't stop the CO2 and if you try closing the CO2 like, it will explode. With any DIY or system like that, it needs to run til you replace the contents.

But you can have the diffuser on a timer, and at night, it'll just bubble the CO2 to the surface with the powerhead off.

If I am correct, a diffuser is a part for the CO2 system with no power supply. How can I plug in a no-cord diffuser into a timer outlet? This isnt an ordinary CO2 canister. Its different and everywhere I read online that sells this either says to plug into timer or unplug during the night.

This is interesting, but I am leaning toward the CO2 from eBay that someone posted on here.

I just read the details, the powerhead inside the tank are the one that will be turned off at night, but the CO2 will continue to release C02, bubbling up to the surface.

Does she leave it on during the night or unplug it or have it plugged into a timer?

She leaves it on...it doesn't produce enough CO2 to affect the oxygen levels in the tank.

The venturi diffusor is plugged in. You can turn it off and CO2 will still escape (so it won't explode), but I would leave it plugged in...it shouldn't hurt anything. If you worry about the fish at night, just add an airstone to run at night.

It depends on what kind of diffusor you use. Most diffusors aren't plugged in. The one that comes with the Red Sea system is kind of like an airpump. It forces the CO2 into the tank with air. The instructions for the system do recommend you turn it off at night, but really it isn't necessary. If you worry, use an airstone at night to outgas the CO2.

The powerhead (aka Venturi) is the diffusor.

Kristin, I think you deserve to pet my bunny. :p Okay, you can hug him!

I am curious about something. During the day, with this specific CO2 system, it will adjust the PH to the desired level. However, at night, with an airstone running, much of CO2 will escape the water, how much effect will this have on the PH level?
