I have been shopping for a Zeo lite media reactor that would suit my needs. The problem I have run into is of the available reactors currently for sale are to be used in the sump. I have a nano cube tank with a small sump. The available real-estate in the sump is taken by my return pump & skimmer. I saw that Avast used to make an automatic external vibrating unit. Unfortunately it's no longer produced not to mention pricy even if it was avail. So my work around is to utilize a plain Jane carbon / GFO reactor and mount it to a lab vibrating mixer I found on Amazon. The more I think about the more I like the idea. Since I have the Hydros system available I could plug it into the Wifi power strip and set it up to turn on/off automatically. My only concern is how to keep the reactor from vibrating off the mixer. Has anyone done something like this before? Thoughts???
