I posted this thread in general disscusion so reposting here as i may get a better response. Please close original thread.
Firstly ill give you some info of my tank.
Fluval roma 125
Filter is an all pond solutions ef 1400 with uv carbon is removed with extra bio balls added.
Lighting is stock t8 2 brand new bulbs one aqua glo one power glo.
Substrate is unipac aqaurium sand.
200w heater set at 26.c
Tank is planted moderatly id say but plants need to grow out yet.
6 rice fish
6 harlequin rasboras
5 cardinal tetra
3 peppered corys
a pair of bolivian rams
Ok i have been looking at the hagen natural co2 system to help my plants along. I read that in order to determine your co2 you must know your ph and kh.
So i have tested both, my ph is 7 tested with both ph strips and hagen liquid test kit. Kh also tested with hagen liquid test kit comes out at 8 degrees.
Now according to charts i have seen that would suggest i have already got 25ppm co2 in my tank without injecting any co2 is that right?
Or am i missing something here i have to admit i'm a little confused.
GH is 14.4
KH is 8
PH is 7
Does that make my co2 25ppm?
