water parameters opinions please

kh 10degrees
gh>14
no3 10
no2 0
ph 7.6
c12 0
ammonia 0

here are my parameters im trying to get my c02 set up correctly...my drop checker is in the green but using an online co2 calculator im getting 7.5 ppm
which is low...i should be aiming for 15ppm?

iv inline co2 difuser and bubling at about 3 per miniute......anything more than this sends out alot of really tiny bubbles...makes the water carbonated looking....what should i do...

opinion on other parameters welcome also

cheers guys

I must say, I was scratching my head trying to figure out what "c12" was for the longest time. Then I realized you must have been trying to write "chlorine", abbreviated as Cl2 (lower case L, followed by (what should be) a subscript 2).

Are you using a 4 dkH reference solution inside your drop checker? If so, I would trust that more than the online CO2 calculator, as their results can be affected by factors that alter your kH.

+1 trust the drop checker first. Most people aim for around 30 ppm CO2.

Increase the CO2 slowly. Watch the fish through a day or two. Then increase it again.
Do this until the fish do not like it, and back off a bit from that. When the KH is so high, I do not think you are going to see much pH change, even adding CO2.

I'm using a premixed 4dkh mix from co2 art and is green...is there any level I have to be careful of while increasing co2....my tank gets fairly carbonated look if I go more so I'm going to put the inline diffuser before my eheim canister as this will diffuse the bubbles more

I prefer Diana's method to adjusting CO2. Both the drop checker and PH/KH relation are fairly inaccurate. Ideally you want as much CO2 as your inhabitants can tolerate. How close to that level you want to keep it is up to you. Remember CO2 levels can change from many factors. So leaving a little wiggle room is always a good idea so you don't gas your fish when conditions change.

The only level to be careful of is when you fish start to complain. Use them as your "level indicator". Then the drop checker or PH can be used as a reference point.

Using this method, I've never had a green drop checker. Mine have always been yellow. I call it my canary. If it isn't yellow I have an issue.

If that doesn't work you can try a CO2 reactor. They are pretty cheap to build or buy.
