Hi All
I am running a Juwel Rio 400L with UV, External Ehiem Filters (2215 + 2213) which is heavily planted. Lighting consists of the standard unit with one Triton and another plant growth tube (reflectors are also added).
My question is, i am looking to upgrade the existing CO2 system (2 x Hagen Yeast diffusers) to something more stable with a higher output.
The plants are doing well but i would like to see further improvement and a lower PH (currently 8.0).
Can someone recommend a suitable CO2 stytem, which will automatically regulate the output at night also?
Also, if there are any good tubes that i can replace mine with (maybe natural daylight ones?) your advice will be most welcome.
Thanks for reading
