Extracting Enviromental air into CO2 reactor
I have designed a DIY CO2 reactor, which second purpose also act as a Surface skimmer. An L-shaped, dia 1", tubing is connected to the powerhead H2O input, where the other end of tube is pointed to the water surface, acting as a surface skimmer.
It has been using for a month, but has failed to be use as a surface skimmer. However, As the tank water has dry up slowly throughout the days.... I notice reactor extracts enviromental air into the reactor bottle through the L-shaped tube. As hours and days of noticing this reactor extracting and dissolved the external air, I also notice that those plant did grow and pearling do appear at those leave. Including those plants which is far from the reactor output.
I have stop the CO2 input since then. The result was good. ..Ph was at 7.0 , while kH was 3. Based on calclation, CO2 will be 9ppm. Usually, injecting CO2, makes pH to 6.5, gaining CO2 to 28ppm.
Pealing and growth of plants makes me decided to stop CO2. Does that mean that extracting enviromental air has other dissolved compound involved in the reactor? Pls advise for this method of aquatic planting.
