Am I understanding correctly. If I cut my reactor in half I'd just have to fill it more often?? Or maybe not decrease the size, just reduce the media by 2/3 from 8lbs to 2.5lbs. Then it would fluidize and be even more efficient?o2manyfish said:The mechanics of a calcium reactor are not affected by size. A small reactor (size of a coke can) can handle the demands of a 1000g stocked SPS system. However you have to add media more often.
Large reactors just make less work for us.
As for efficiency, reverse flow is usually more efficient than top down flow, and fluidized reactor is usually the most efficient.
Matt,mattseattle said:i have a question about the A.R.M. media. does it have a life span? i bought a used reactor that had the A.R.M. media in it and I don't know how long it has been in there. Does this stuff retain it's usefulness forever?
The shelf life would probably be forever. I would'nt reuse old media or someone elses media. You dont want to reintroduce the funk back into your system.mattseattle said:well that makes sense if the reactor is being used. this reactor had been sitting for quite a while. i went ahead and replaced the media anyway just to make sure it's all fresh. i am still curious though if there is a life to this media.
yep.Am I understanding correctly. If I cut my reactor in half I'd just have to fill it more often??
In order to fluidize the flow of water would have to come from the bottom up. It also depends upon the media type. I use rowalyth and it has smaller particles and is designed to fluidize. ARM are heavier and might not want to fluidize even with reverse flow, it would depend on how much flow.Or maybe not decrease the size, just reduce the media by 2/3 from 8lbs to 2.5lbs. Then it would fluidize and be even more efficient?
To a point yes. If you have a large chamber and it is top down flow only a small portion of the media will be exposed to the lower ph water so concentration would be relient on that. In a fluidized reactor all the media is suspended in the water thus melting all surfaces at the same time..a little more effective. With the small amount of drip rate coming out I dont know how much of an effect the larger chamber and more water would pertain.I think in general a larger reactor allows a larger water volume to be acidified and therefore allows more calcium to be pulled into solution than a smaller reactor. At a steady state, this may make less of a difference since you only really need to replace minute by minute losses of calcium.
