Thanks Craig - Yes, this week I did have a lot of surface agitation. I've
now adjusted the spray bar so that although there is surface movement it is
not heavy enough to encourage air.

With a pressurized system if your having trouble getting the CO2 up. Maybe
you have too much surface agitation.

either make yourself a diy co2 system using 2 litre soda bottles with
yeast
and suger or get a pressurized co2 tank. What size aquarium?

I have a pressurised CO2 system and have been using it for a week now.
Aquarium size: 400ltrs
