REACTORS- Filtration for stingrays
- Thread starter DIDYSIS
- Start date
Why would we trust someone that says moving beds are "rubbish"? Why would we trust someone so capable of pointing out flaws yet incapable of fixing them? IF you got all these problems nailed down then why don't you have a working moving bed? Was it just easier to convince yourself that what you already had was as good as it could possibly get?
"Traffic jams" happen for a reason. Either fix it, or convince yourself it's just part of life and there's nothing you can do about it. Either way fixes it, but only one gets you a working reactor........
as stated over and over again i have a sand bed filter running which in my eyes is much better than moving bed which gets stuck in a traffic jam
the idea of moving bed and sand filter is the same but the sand moves more freely with no traffic jams so why would i need both
in respect to sand and k1 k3 compaired to sand then moving bed is rubbish
When the power goes out sand filters compact and without intervention may not restart.
I'm sure yours doesn't do this, but I know several people that gave up sand filters cause of the inability to properly restart after a power cut and thier own compacting version of what you would call a "traffic jam"
Kind off odd that several of us here have no "traffic jams" in our reactors. Maybe we should try some smaller air pumps........

wheres the super oxygenation in a sand filter? part of the theory of a reactor is using oxygen to move the media! there is no oxygenation in a sand filter (to my knowledge) and as stated above, when theres a loss of power, the sand can settle and not fluidize when power is returned on.in the event of a power loss, a battery powered air pump would keep bb alive in a reactor until normal power is restored. for me, sand is a waste of time.so far, i have yet to see anything better than a fluidized bed reactor!
if the ox is so great from a moving bed then you should all have very high redox levels please tell me what readings you are getting
i have had multi air stones in my sump to air the media long before a moving bed
the trick with a sand filter and stopping it compacting is to have a tall tube not a short tube with lots of sand in it or of course the pump wont be powerful enought to get it moving again after a power cut
i turn my sand filter pump off all the time to back wash the pump with no problems i also get a lot of power cuts thats why i have bat backup
i can now turn this round on you DB like you told me my reactor was not set up right i can say to you if your sand was compacting then it wasnt set up right

as for using a smaller air pump maybe you should try using the same size i was using
i use 2 of this pump on my tank and when i was running the moving bed one of this pump was running just 6 air stone its not a small pump

and not cheap at $150 after all you get what you pay for dont you
90 liter per min to boil how much media? 2 ft3?
Seems like 65 lpm for a moving bed would be a waste of time......
T1, looks like that pump is rubbish. I don't think I paid $150 for my 149 lpm pump and I thought it left some to be desired in the electricity consumption department as it sucks 100 watts to make that 149, but I guess that's pretty good compred to 60 watts to get 65 lpm.
Maybe I'm missing something?
In regards to the sand filter, I've never ran one, probably never will. Like I said, known people that have ran them and they hated them. I'm perfectly content with what I'm currently working with for bio, just need to get the mechanical side of things figured out.......
your right is was you get traffic jams90 liter per min to boil how much media? 2 ft3?

BUT is you read the spec of my pump right thats 65 lpm at 3.5m i was only running it at 12" so you can probably double that output
what is your redox please dont tell you dont check it
mine sits on 280 mv with all the air stones in the sump and tank
with ozone it should sit at 300 mv
if your reactors are doing such a great job at putting ox in the tank you should be hitting 290 mv which is more than mine but less than ozone
Well, after a couple of trials, and an overflow accident, i resolved the traffic jam issues. Media is now constantly on the run, boiling.
I shoild point out that i reduces the media to 3/4 of the initial gallonnage i bought, and will add the rest slowly.
This was pointed out by Dyodysis and it improoves the effectiveness of the reactor.

Do you really think that 65lpm will do the job in a square tank? And yes 2ft3, I always figure having more then enough is far better then having too little. but its more like K3 the media is a little larger so might take a little more work to boil I don't know. I am thinking of making a little pipe system( under water spray bar pointing up) and just trying a water pump and will see how that works with the small air pumps I already have around it. Then again looking at it my pump is like 5lpm and moves a bit of media right now so 65 or less would probably work really well. The commercial air 3 with 35 Watts and 65 lpm sounds like an idea.
