 where is this sold?
I did find the Hydor system at Big Al's, as I've not seen one in person, and where is the Exclusive system sold? I'm curious.
I ran a Hagen CO2 sysptem on several tanks. As I see it, the Hydor system may or may not have a larger generator. I'd be nice to know the volume of the canister for that will control how much gas you get from the yeast.
This Hydor seems to have some sort of a powered diffuser? or just a microbubbler? hard to say. I know that my yeast powered units (I had several different types) tended to get a bit of "snot" inside the tank if there was no bubble counter/scrubber (where the gas flowed through a bottle of water that allows you to see the rate but also served to remove any escaping yeast, the bottle is easy to dump to clean, you don't want that yeast inside the fish tank) An airstone or sintered glass airtsone always got plugged up, I suspect a microbubbler would as well. That was one of the cool things about the Hagen unit, any snot that got into the tank would just collect on the end of the tubing and not mess up the travel of bubbles up the ladder.
When you use a powered reactor on a yeast system you add a bit of backpressure to the unit which works against you somewhat. It may not be too important, but you can observe this when the tubing has just water in it.
Sorry this was not more helpful, I've not actually seen the unit you are talking about. |
