Before anyone hounds me I have said it before And il say it again I know this is a saltwater forum but I call this place home over other forums and threads I find it alot more supportive and more knowledgeable than other forums. So I come here to ask questions as I'm sure most of you had FW before salt not all but most. So here's my question. I recently just got my CO2 running for my 55 gallon planted aquarium. I have a Coart dual stage regulator and a 5lb tank. So I'm trying to get to that 30ppm range when my lights turn on so my plants hit the ground running. But I have been turning on CO2 2 hours before lights come on. And around mid photo period is when my bubble checker actually turns green which is the good zone for CO2 saturation in the water and won't kill your fish. I don't have a lid on my tank and I have a few HOB filters so surface agitation isn't to much. I have a HOB outflow pouring right onto my diffuser so the CO2 bubbles aren't going to surface immediately. I'm at about 2 bubbles per second right now on bubble counter and about 25-26 pounds of pressure running from CO2 tank. Is that not enough for as big of a tank it is and because it doesn't have a lid? Should I maybe start CO2 3 hours before lights or up my bubble count? Any tips would be appreciated! Thanks! Happy reefing and happy FW planted fish keeping idk lol
