Nano DIY c02 and other higher tech questions
Well this is my first foray into higher tech tanks. I came across a 5.5 gal tank a while ago and decided to bring my hobby to work lol. I have a very sucsessfull low tech 36 gal tank going at the moment, but decided to step it up a bit for my 5.5. I currently am doing DIY CO2 injection. My main concern is with air exchange. I have a Plexiglas top made by my father in law on the tank. There is only one small cut out to let the equipment come from under it. I have been filling the tank all the way to the top and get a very nice effect (think edge) My main concern is with the air exchange. The CO2 is able to stay in the tank for very long periods due to it being trapped against the top. Eventually the bubble will get big enough to roll over to the opening left for equipment and roll out of the tank. Now my main question is with the O2 being introduced or lack of O2 to be absorbed in the water due to lack of surface area being open to the atmosphere. Is this something I should be concerned about? I just pulled a handful of rams horns into the tank to help with my algae outbreak, I did notice that they go to that one area of the tank where the equipment is, they do not seem to be trying to crawl out of the tank, but just sitting there against the surface of the water.
My second question has to do with my marsilea quadrifolia in the 5.5. how long does it take to convert to the aquatic form? I have trimmed off the long stems, but the darn thing keeps sending more up lol.
