It could be that your regulator can't produce enough pressure to give any more than 1bps. What regulator are you using, can you adjust the working pressure at all? Some of the up atomisers need more than 2 bar to work properly.

The colour didnt change even when i wasnt using inline diffuser, its getting to make or break time, im out of ideas, just doesnt seem to change watever i do,
I've failed with CO2 in the past and it's been because of this sort of logic. If the cost per bubble is worrying you, you should get a bigger bottle or find cheaper ways of getting it refilled. Honestly mate, you can't have a mental block that stops you getting the tank to the optimum levels for your plants. Been there, done that.belly259 said:dont wanna go ecessively open or i will end up emptying cos bottle in no time

It doesn't need to be in the flow. Anywhere that's convenient to see will do really. If the flow around the tank is good, the CO2 gets distributed. They do take a couple of hours to change colour though.
