While you can use a Y connector to combined CO2
production from two DIY CO2
bottles, you really can't use the same methode for splitting the CO2
output to several tanks and/or diffusion methods in the same tank. The problem is that the pressure won't be the same on all the lines and you'll end up with one getting practically all the CO2
. The only way to split the CO2
output is to use a manifold.
Unless you have a really large tank where it's harder to distribute the CO2
evenly through the tank with a single input, there's no reason to use multiple diffusion units (methods). CO2
Mist is supposed to be one of the most efficient methods, but some people find that it can be a bit of an eye sore with all those extra bubbles floating around. An inline reactor while not quite as effective, is generally plenty effective for most people.
