Best way to know you're at 30ppm Co2 or optimal co2 levels
So I know this has been talked about 1000 times on here, and Ive dont plenty of searching...but here's some questions based around my tank specifics
My 40B has been set up since early November. I run pressured Co2 with a Red Sea Pro Kit. It consists of a regulatror (plastic and cheap), needle valve (plastic and cheap) (bubble counter, yes) and diffuser pump. I have since switched to Cerges reator for diffusion.
Im just waiting on a Swagelok check valve, but I have a nice Victor dual stage reg, parker metering valve, burkett solenoid and JBJ style bubble counter that I will be installing this week.
I'm assuming this higher quality setup will give me more constant co2 metering. Im pretty sure the cheap needle valve that came with the Red Sea Pro Kit isnt that precise.
Is using 4dkh solution and a drop checker the best way to get the lime green that indicates 30ppm? Is it ok to have more than 30ppm?
Im trying to dial in my co2. I run 4x39W T5, dry ferts EI, and the bottle. I have algae issues (staghorn and stringy brown algae) so Im playing around with my co2 levels. In reading around these forums, I see Tom Barr saying that if your co2 isnt right, you'll get algae. Thats why Im focused on my co2.
If I take a cup of water of my tank and let it sit 24hrs, the pH is like 7.2. If my in-tank pH probe is reading 6.2, does that mean for sure that I have 30ppm? Ive gotten it down to 5.8, would that be approx 45ppm? How do I know my ph levels are constant?.
In the meantime while I have this algae, i cut back to 2x39W.
