Judge my drop checker colour please

[creg]

I am a little colour blind I think, is it blue or green?

 

[Crusader58]

It's Green

 

[creg]

Thanks, is that the optimal colour then?

 

[Andy Thurston]

I would say its green but only just. its certainly not starting to go yellow yet and you could add a little more co2 if you want. If you do want to add more co2 then do it when your around to observe your fish just in case you add a bit too much

Thanks you've answered my question too mines the same colour and it looks more blue/green but I've got a lot off neons in the tanks best to air on the side off caution.
May up the co2 when I'm around to see how the fish react.
