Take a spin with nifty DIY horizontal Zeo reactor

By Brian Blank on Feb 12, 2010

We love seeing ingenious and interesting DIY designs possibly even more than some of the great new products we come across daily and this DIY horizontal Zeovit reactor from Sweden definitely gets our DIY juices flowing. This is a fine example of DIY workmanship from the acrylic fabrication to the electrical and mechanical aspects, it’s one beautiful piece of DIY art. We don’t know too much about the creator “cwrang” but we like the rotisserie approach he came up with to keep the zeolites in motion. As with anything mechanical, the more moving parts means more possible points of failure and this DIY job has a couple possible places where it could go wrong but it still is a great bit of DIY. We just hope the access door seal hold up well over time but it appears to be a nicely sealed and tight. Great job cwrang, we would definitely like to hear how this unit holds up over time. Check out another short video of this unit after the break.

Well, interesting. But, how does the water enter and exit this unit??

I would assume water enters or exits through the fitting you see on the “film1″ still shot above

I call it the Model A ZeoTooble. Sealess bearing from acrylic for hose fittings? No thanks.

and after about one week of use the hozelock fitting on the end will wear and you will come home to water pee-ing everywhere, not to mention an acylic tube that looks like its been used as a gem stone polisher.

10/10 for cool concept

0/10 for practicality

Thanks for the feedback of my DIY zeoreactor. The prodject is on ice just now. I dosent have a tank in my new house. It works great but I have a little problem with a leak in the lid where you fill in the stone.

Christian, great job thinking outside the box and trying something unique and different! Maybe for the next version using an access from the ends would work better.

I think I saw someone make something like that on RC 6 months ago (maybe the same one?).

The problem is that the water will take the path of least resistance… going in one end, over the stones, and then out the other end. Maybe with some alternating vertical baffles throughout the pipe the water would be forced to go back through the zeolith, but it would also make loading/unloading a challenge.

I never got a clear answer if ammonia does adsorb to zeolite. Does it just retain bacteria? I’ll take brown over bleached any day, so just curious.

@green_apple:

Zeolite works differently in saltwater than freshwater. In freshwater, it rapidly adsorbs ammonium on it’s own. In saltwater, it’s the biofilms that develop on the media with the additions of bacteria cultures and organic carbon that are primary “nutrient reducers.” Some tanks running with high nutrient levels for long periods (years) can react badly to Zeolite filtration, but this is usually a result of “over zeolizing” too quickly. As with everything in this hobby, slow and steady migration to this method is key.
