CO2 amount for 3ft tank

[Halimlee85]

Dear bros,

I recently bought a co2 tank to ensure a healthy growth of my planted tank plant how ever i not really sure the right amount of co2 that isurpose to have.. i having a HC grass, glasso and variety of mosse what will bethe ideal co2 i should have?

Thank you in advance!!

That depends on the amount of plants and the intensity of your aquarium light. Basically more light , plants take in nutrients faster ,consumed more co2. roughly like that ar bro hehe

Hi Halimlee85

May i know what your co2 tank spec? electric or manual solenoid? :0

[Halimlee85]

my CO2 tank spec is 2L using a electric JBJ solenoid.

Thanks bro but the proble is how much more is more? it puzzle me also. i did have the CO2 Checker to ensure it suffient however it is a good indication to dictate if it a right volume?

the plant i have is Glasso, HC, hair grass and other type of mosses like Java, Fissiden, Christmas Etc...

I think if you have a CO2 checker.. Try monitor the color.. It should be blue (low co2 - morning), green (just right - afternoon), slightly yellow (high co2 - evening before solenoid cut emission).. This is based on my current checker solution..

On my 2ft tank with HC & rotala, I m only putting 1.5bps to 2bps to achieve this result..

unfortunately bps does not mean anything, it is not the best way to measure CO2 concentration in the tank. With the same bps you can get different CO2 concentration when you are using different reactor or diffuser. Drop checker is so far the best provided you are using kH=4 solution. You can't use your tank water because kH and pH most likely affected by soil.

Note that drop checker is not real time, it will take sometime before the color change.
