4 kg CO2 in 4-5 weeks?

Hi

Info:
65g tank, 4x39W T5 ( 9 hours ), pressurized CO2, AM PH controller, AM 1000 Reactor
PH 6.7 KH 5,5 (tapwater PH 7,5) , dosing EI
Moderatly planted, ( Eusteralis stellata, Rotala rotundifolia/Macrandra/wallichii) and some more.
My tank is absorbing 4 kg CO2 in 4-5 weeks, is that alot of CO2 or just normal ?

1kg is roughly 2.2 pounds, right? If so that is a lot. However, I do not think your tank is using all that CO2, you probably leak. Spray soapy water on the brass connections and solenoid to find it. Also if you have a bubble counter make sure the O-ring is not missing, is seated properly and that the connection is on tight.

Another thought, I see you have a Ph controller. How much surface disturbance do you have. If there is a lot of surface disturbance you Ph controller will have the solenoid open, fighting the out gassing caused by the surface disturbance to lower the Ph to your set point. However, if I was a betting man my money would be on a leak in the system.

I`ll use soapy water trying to find a leak ( once more)
There is only wery little surface disturbance.
I dont have a bubblecounter, but I can count the bubbles i the reactor, and it is 3 buble every 2 sek.when the solenoid i open.The solenoid is open 50% of the lightperiode

1. Use a new seal/gasket on the connection every time you replace the regulator (this may not apply with European cylinders).

2. Make sure you use a wrench to tighten up the nut on the regulator. You are not going to break it so get manly with it.

3. What kind of tubing and how much are you using?

I did find a leak, this time I blocked the silicone tube from the solenoid, and there it was.
Thx for Your help

Get better tubing. Silicone will lose just about 20% of your CO2 per meter.
