I have just stated adding co2 to my 126 litre tank again after giving it an overhaul with new substrate and plants. I have good flow from my filter with spray bar positioned on the right top end, the stream reaches all the way to the other side. I have co2 diffuser low down on the opposite end to the spray bar, and a power head on the back wall above the filter inlet to catch the co2 bubbles and push them out across the tank. I can see the bubbles in the water, they aren’t as dense at the end furthest from the diffuser tho. I have a drop checker each end but
neither ever goes green, and I’ve tested ph before co2 starts, again 2 hrs later just before lights come on and and again just before it goes off 10 hours later but it doesn’t change at all. I’m running 120 bubbles per minute which should be enough, can anyone tell me what I can change in my set up to improve co2 saturation? Also is there another way of testing co2?
