water parameters

[simon Coram]

What water parameters should i be aiming for,
mine is
ph 7.9 a few days ago it was 7.6
kh 13
gh 3

my drop cheaper didn't change colour still stayed a light blue colour after the co2 has been with the lights, its being defused in a inline up diffuser.
its been doing about 1.4 bps.

I've got tetras in the tank so dot want to overdose on co2

We need more details about your setup to help you.. tank volume, lights, filter and so on...

It's a 180ltr tank with two T5 tubes.
Two external filters.

Since planting the grass carpet last Thursday I have noticed some runners a few cms coming off them.

Water parameters are irrelevant and won't make any difference to your drop checker colour. I would suggest, most likely, if your drop checker colour is not changing, you have a CO2 leak somewhere.

If I run at around 1-2bps, with inline diffuser and 180l tank I get a beyond green drop checker. Fish don't seem to mind too much.

If you breathe into your drop checker for a couple of minutes, especially the above JBL ones, you can quite easily get the blue indicator to turn green to prove your indicator solution is working.

I did work out yesterday I didn't have the pressure up high enough on the co2 reg so have raised it. Will check for leaks.
I cans see fine bubbles coming out the filter exit pipe
