  • How much CO2?

    I finished my valve for my paintball CO2. I got a disperser for it. How many BPS would I need for a 5.5g Nano tank without suffocating my rili shrimps?

    I am pretty sure you measure the ph of the tank don't quote me on that. Just start real low and adjust till the PH of the tank is where you want it.

      Bubble count is meaningless for setting the co2 in that tank. As Nick suggested, start slow. Get a baseline ph of your water by setting a cup of it out overnight, then testing ph. That's your starting point. Most folks try for a co2 sat of around 25 - 30 ppm. Dropping the ph a full log, slowly, with co2 will get you in the ball park. A drop checker can show you a visual gauge of where your co2 is and a ph monitor can give you a pretty exact reading. It depends on how much you're willing to spend and how accurate you want to be.

        City pets sells a drop in that turns green when its good and red when there is too much. With a tank that small why didn't you just dose excel? Also, what kind of filter do you have on this tank? A hob will cause the co2 to gas off....

          Also depends on the critters in your tank... What PH level they can take... You have to go slow to fast and they will go belly up.

            If you really want a starting bubble rate, begin with less than 1 BPS, then check your pH as mentioned above. It's best to get the CO2 figured before adding the critters to the water. Fish are easier because when the CO2 saturation it too high, they'll let you know by gasping at the surface. Shrimp...not so sure.

              Right now I'm running a Nano 501 canister filter on the tank. What does dose excel mean?

                The shrimps seem to be fine after a night of 1bps. I have yet to check the pH of the water, but I thought co2 wouldn't cause a major drop on pH.

                    Co2 Will drop your ph really quick...

                      Well, now I know from experience. I'll try that Liquid Carbon on the nanos, I've moved the CO2 to the 30 gallon tall.

                        Yea learning Co2 would be better on a larger tank more room for error

                          I will start checking pH for the right amount of dosage of CO2, it should be beneficial if it drops a little bit in my 30g Tall, angels like low pH right?

                            PH and co2 are inversely proportional in your tank... the more co2 you add the lower the ph goes. co2 and water form carbonic acid. If your base ph is 7.6 then adding enough co2 to put 30 ppm in solution is gonna drop the ph to around 6.6

                              be careful with excel and other carbon liquid ferts to much can kill your fish and shrimp.
