Those are strange numbers for a cycled tank

CO2

My 10 lb. CO2 tank contains (10 pounds) of CO2 at 800 - 900 pounds "per square inch" pressure. I sleep better knowing I do not have a bargain basement regulator on top of that baby. $90 - $125 is a good price for a good regulator. The regulator steps down the pressure to 25 pounds per square inch of usable pressure for injection into the tank.

I pay about $50 (one time charge) for my tanks, which I take back to my local industrial gas company and exchange for a full one when empty. I pay about $15 for a refill + tax +hazardous material fees + new connection washer...about $22 to fill the tank. I blow thru it in about 3 months.

Therefore I have no brand to recommend as my system is put together from components I judged to be reliable. I will tell you my regulator is Azoo and I have had no issues with it for two years. My tank is from my local gas company.

I know there are several threads in the planted aquarium sub forum that discuss injection. I use a DIY micro misting system which works well for me.
There are more than a few systems which planted tank forks use or experiment with. Do some thread reading and get a feel for it.

what should my lvls be?


should i start doseing?

Jay

If you have a high light tank (over 2.5 watts per gallon) and
If you are planted out to about 50 to 60?

you could start CO2.. The level should be a Max. of 30 ppm.
and you can experiment with nutrient dosing

Otherwise use Seachem Excel. and follow the dosing instructions.

Dosing nutrients: As with all of this, there is no do this ABC, it requires hands on tweaking and experimenting until you plants tell you they are happy. What works in my tank may be a little different in yours.

Here is a thread where nutrients are discussed

Here is the web site for a very well respected planted tank expert. It is a good read. Some of the information is a little old, but most of it holds up
