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

sorry....its a 90 gallon---48"x18"x24". The plants I don't really know what types yet I have some what I think are Vals and some Java Moss and I don't know what the other is but I am redoing my aquarium and want to add alot of different types of plants.
If you need any more info let me know.
Thanks
Gary

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.

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....

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.

A ph controller is not necessary. If you get one, it's just one more thing to do maintenance on, as it needs to be periodically calibrated, and the probe needs cleaning on occasion. I used to use mine, but have removed it. I run everything on a timer so when the lights come on, so does the CO2. And the CO2 shuts off at night when the lights go out.

Well I just ordered the regulator that you recommended now I have to get a tank and a stone. I have a canister filter so I guess I will run it under the intake of that and just do it that way. If that doesn't work to my satisfaction I think I have a powerhead in the basement that I can use. What 3 things or 4 or how many ever should I be running in the canister for best plant growth?
Thanks for all info it has really been helpful

Once you get it set up, look to start at about 1 to 1.5 bubbles per second. This should give plenty CO2. Also remember that if a tank get's pretty thick, in other words, heavily planted, I would run an airstone at night, or a powerhead directed at the surface, to cause aggitation. Plants produce O2 during the day, but use O2 at night, and could strip the O2 from the water, killing your fish. I had this happen when I was very heavily planted. But now I run powerheads that ripple the waters surface, and have not had that problem.

As for running it during the day, you can. But remember, more surface aggitation requires more CO2 to be added, or a higher bubble rate. You don't need any surface aggitation during the day, but I recommend it after lights out.

Lastly, BBA is caused by a fluctuating CO2 level. If your levels are too low, and keep dropping out, you will get BBA in due time. Also, have a ph and kh test kit to keep tab on your CO2 levels until you get your bubble count to the desired level. Your goal is a minimum of 30ppm, up to about 50ppm. This will give the best plant growth, IMO. I generally keep mine at a minimum if 45-60ppm, but I'm probably running a ton more light than you will be, as well as have a much more densly planted tank. But the minimum should never go below 30ppm. Some say 25ppm, but I like being a little more than bare minimum. lol.

And remember, feel free to ask any questions. We are here to help where we can.

CO2 and aeration

I'm looking to get CO2 to lower my PH and get some plants. If I keep using my air pump how will that affect the CO2 i want to put into the tank? Will it be a waste? Will i need to monitor when i use my air pump? i don't think the CO2 pump has a way to control how much. I don't have it yet. Don't know if store carries it or not.

That's what i'm looking at. Thoughts???

Running and airstone during the day would defeat the purpose of having the CO2 injection. The surface disturbance would only gas off the extra CO2 and would diffuse a lot of the CO2.
