  • Advantage superior to Hydrosystem Superdos
    As a wholesale greenhouse grower, we moved to the Advantage line from Dosmatic several years ago because of injection issues during low flow in Dosatron injectors which we were currently using at the time. Unfortunately Hydrosystems bought out Dosmatic several years ago and ceased production of the Advantage Injector, replacing it with the Hydrosystems Superdos. What we discovered is that the Superdos failed much more frequently, bled clear water back into the concentrate tanks and an overall had much higher maintenance requirements. But the single most frustrating thing about Superdos injectors was the inability to inject enough concentrate under low flow rates because of its failure to pickup enough concentrate. So needless to say I was overjoyed when Hydrosystems decided to begin manufacturing the Advantage line again. I have begun replacing my Superdoses across the range with the Advantage injectors which run the same injection rate under low flow as high flow, having verified this with PH and EC testing. When testing the Superdos injectors the mix would get unacceptably weak with lower flow rates. I also expect to have significantly less problems with the Advantage injectors if the new Advantage line is just like the original from Dosmatic. Time will tell.
