I am getting water coming through the ceramic tube and filling the diffuser and co2 line over night, is this normal or do I have a problem somewhere, I have checked for leaks but found none Phill January 10, Jenkins, I prefer to have my CO2 diffuser on the end where filtered water is entering the aquarium, away from the aquarium drain/ suction to filter. One question though regarding the inline diffuser. I have just started with co2 and have bought pretty much all of the above. Start slow, with less than you see recommended and increase slightly the following week, and so on.įantastic guide, thanks for the effort you put in. My heavily planted 170 gallon tank, I run 4-5 bubbles a second. ![]() ![]() Nano tanks under 15 gallons I might do 1 bubble ever 2 seconds, etc. Generally, I like 1-2 bubbles per second for most planted tanks under 75 gallons. There is no hard and fast rule when it comes to how many bubbles per second you need for what sized aquarium, this is where feel comes into play. One bubble a second is a good start for smaller aquariums ~20 gallons or so. You should adjust this knob to where you able to count individual bubbles. Slowly open (counter clockwise turn) your precision knob and watch the bubbles begin to enter the bubble counter. These small changes won't end up making a huge difference, it's totally up to you. I like to have my CO 2 start up 2-3 hours before my light comes on and then have it turn off about an hour before the lights go out. If your LED is controlled via an app, just make sure your timer for CO 2 is synced up to be on when your light is on. The easiest way to sync up your CO 2 with your light is to have them share the same timer. Plug your solenoid (A) to a wall outlet or timer (recommended) and make sure the timer is set to an On period of time. If you have both option readily available, you're a lucky person! Lots of times you can purchase tanks from these local stores as well, just remember if you buy either online from Amazon or anywhere else for that matter, the tanks are shipped empty so you will have to still go get them filled. If you want to go the larger tank route, investigate your local welding supply or home brewing store and make sure they can fill or swap out big CO 2 tanks (most do). This can be inconvenient so I make sure to stock up and have about 3 extra filled tanks ready to go. If you are wanting to setup multiple tanks or an aquarium(s) ~40 gallons and up, a larger 5lb tank meant for a kegerator is the right choice.įirst check what you have easier access to- I myself don't have a paintball/airsoft store in town so when it comes time to refill my smaller tanks I have to drive an hour away. If you have an aquarium less than 30 gallons, the smaller paintball setup is the way to go. ![]() Convinced yet? Well, If you want to get rolling but don't know what you need to get started, lets solve that!Ī few option are available, however I feel the the best choices are either a traditional 5+lb tank or a 20oz paintball tank. It appears that the addition of CO 2 helps drive the uptake of NO 3 - and likely other potentially harmful compounds in our aquariums! This is just a small example of what adding CO 2 can do for the health of your planted tank. Tank 2 did not require a water change because there was no NO 3 - present. Tank 1 required a water change about 20 days into the experiment as NO 3 - levels were approaching 30ppm. ![]() NO 3 - was accumulating with time just as we are taught about in the typical aquarium nitrogen cycle. However, in tank 1 we saw a more familiar story. Based on periodic testing of both NO 3 - and Phosphate (PO 4 2-) I was not able to detect NO 3 - or PO 4 2- in tank 2 at any point in the experiment. Another big finding from this experiment was the observation of no accumulating Nitrate (NO 3 -) in tank 2. Simply adding CO 2 made the red plants redder and the carpet plants spread out to fill the substrate completely. Not only did the plants in tank 2 grow faster and overall much larger, they appeared to be more healthy based on their coloration.
