co2

I was thinking of adding co2 to my aquarium. I was just wondering what type of setup to get. I was looking at a carbo plus setup on ebay but I don't know anything about them and was wondering if they were a good way to go or would it be better to get a pressurized setup and which one if so.
Thanks
Gary

giving us some information about your tank would really help like the size and what plants

Pressurized for sure if you can afford to get it. 90 gallon is way too much for a little DIY setup to handle and keep levels steady. It will make life a lot easier and in the long run is less expensive to run than DIY or any other system sold.

Diffusing it is also easy, the newest way seems to be the CO2 mist method where you use a powerhead and spray the bubbles down to the plants and under their leaves. I will see if I can find some other devices that are successfully used.

For a 90G, pressurized is the only way to go. Here's my setup....

10lb bottle
Milwaukee regulator, solenoid, needle valve, and bubble counter combo.
CO2 line
Limewood airstone
Powerheads

This is probably the easiest method, and very effective. Run the airstone under the powerhead intake, or if using a canister filter, can rn it under the canister intake. Using the canister will difuse the CO2 into the water, and using the powerhead will create a CO2 mist that is sprayed arount the tank, and when the mist hits the plant leaves, it is very effective. I get the best growth using mist.

Other ways to diffuse the CO2 is Inline CO2 Reactors and Powered Reactors. Some can cost much more than others.

Even though it is the same planet, underwater is a whole different world.

Go Presurized. The Carbo is not what it is said to be. And they really don't last. I've read a lot of negative things on it. If anything, go either Pressurized or DIY with 6 bottles.

Well I guess I will go with the pressurized setup then. I am totally stupid when it comes to this so I need to know exactly what I need to buy, where the best place to get it is and how to set it up. Any and all help is greatly appreciated.

I have had a planted tank for several years now but the plants just never seem to do real great so I am totally redoing my aquarium and I want to do it right this time.

Thanks
Gary

The best place to get the tank is locally, at a welding/medical supply store. As for the rest, look at Ebay. I'll get you some links here of what I have on mine....

Regulator -

Limewood Airstone -

Powerhead -

What you do is follow the instructions closely when installing the regulator on the tank. If you don't, and one of the valves is even the slightest bit open when you open the main valve on the tank, you will blow out the guages. If you get the regulator and need help, I can help you get it set up at that time.

Also, when putting the regulator on the bottle, it needs to be really tight. Use the proper wrench for putting it on. Also, if you have a bottle of Windex, you can spray it around the connections, and if it's not tight enough and is leaking, it will bubble.

Once the regulator is on and the valves are closed on the regulator, open the main valve on the tank. Then check for bubbles by spraying with Windex on the connection. If no leaks, then go ahead and fill the bubble counter with distilled water, put the cap back on, install the CO2 lines and airstone and powerhead. Then you are ready to turn the CO2 on.

On the milwaukee regulator, the first step is slowly turn the big black knob on the front (opening the valve) til the secondary pressure guage reads 8-12psi. Once there, slowly open the needle valve til you get about 1-1.5 bubbles per second. Then you are set. Monitor your CO2 levels in the tank, and if it's not enough, turn the bubble rate up a touch. If too much, turn down a touch. Withing a couple days, it will be set and you won't need to mess with it much til it's time to refill.

Even though it is the same planet, underwater is a whole different world.

Do I have to use a ph controller with this setup or is it not necessary?
Thanks
