HI there
I have recently set up a 75 gallon planted aquarium and i am injecting Co2. when the lights go out
i have a air stone come on the co2 shuts off . the ph is 6.0 KH 1dkh (that gives me co2 30ppm i believe). in the morning ph is 6.8 is this kind of flux good. and could i use CC to raise KH and PH
so its not so low.
thank for any input
mike
PS. sorry for beating a dead horse

75 gallon tank
4x32w T8 (4')
co2 injection
Kh 20ppm(1dkh)
Ph 6.8 before co2
Ph 6.0 or lower after co2

I'd say those are pretty good readings, IMO. Do you use a drop checker btw? sometimes it's always good to have one in handy just in case co2 goes out of hand, in the meantime; good luck.

I just ordered a drop checker should be here soon .........I just thought 4dkh was ideal.

Thanks for getting back to me

Hi mrsols1,

When Tom Barr did a talk for us in September, he stated he targeted about a 5.0 dGH and didn't worry too much about dKH as long as it is above 2.0.

I use Seachem Equilibrium to raise my DGH because they have a dosing calculator. I used to use equal parts of CaCl (Dri-Z-Air) and MgSO4 (Epsom Salt) but Equilibrium is easier.

To raise dKH I use NaHCO3 (Baking Soda); here is the calculator I use for dosing.
