Hope someone can help.
I have a 350l planted aquarium with pressurised Co2. It used to work brilliantly and I have always thriving plants. However, something has changed and it no longer works.
I use a night shut-off valve to save Co2. The problem is that I'm going through a 500g bottle in just a few days. Usually, it lasts several months.
I'm running it at just over 1bar (as per manufacturers recommendation). The Co2 passes through the night cut-off valve, then through a check valve and in to the bubble counter before entering the Dennerle ladder. It appears that when the night shut-off valve opens in the morning (on a timer, connected to my T5's), water has travelled up the Co2 tube within the ladder. I have to ramp up the operating pressure to force the water back down the tube so that the gas can escape.
Increasing the pressure obviously uses more C02. How can I get this back to a fully automated system where I only have to refill the gas bottle every 6 months or so?
