Coil Denitrator

Questions for Olin...

Questions for Olin...

Olin,

I've got two questions about your bucket ---

(1) What is the flow rate you're running through it?

(2) Is the bucket sealed (and exits through a small diameter pipe/tube), or does it just overflow back into the system from the highest water level in the bucket?

I really like (what I understand about) the design --- thanks for sharing.

Thanks in advance,
Bob D.
 
rsman ... did you ever get pics and the new coil on your tank? You said you were going to tell day to day about the cycle of it. Any updates?
 
got things done, have pics, and text and a calculator (.xls) to help, but have been really busy, shud be able to get to it in the next few weeks


sorry :(
 
Hi Bob, haven't checked this thread in a while...It is an open system, the water just flows over the side. Flow rate I haven't measured exactly, but it is around than 10-15 gallons/day. Just a super slow trickle.
 
Ok, this is a little random, but I recently recieved a nice e-mail from somebody regarding this thread about the same time my DNS was changing, so I lost emails that hadn't downloaded to outlook yet! I just had a moment to skim the message so I don't remember who it was from...So if you recently e-mailed me and I didn't write back, I'm not trying to blow you off :) Drop me another line and I will get back to you.
Thanks, Olin
 
Very interesting thread, thanks guys for contributing so much of your time and research to this thread and hobby. Just wondering if it would be ok to routinely open the valve completely for a few seconds to help flush out any build ups of slime or film from bacteria. Maybe just drain this water into a separate container and throw it out. Would this kill the denitrifying bacteria or damage the colonies? Just wondering. Thanks again guys for all the info.

if you built it right, that valve should be open 100% all the time

once the unit is cycled you should open it slowly over a period of 2~4 weeks.

if it wasnt built right and that valve is the "fix" then it wont hurt anything to open it up to clean it out.

that valve is only important while cycling the unit.
 
after re reading and the fact that i havent been responging in a while, i figured its probibly best to clear something up

DONT leave that valve full open right away for a long time, even if you have had it forever. if it was not full open then after "cleaning" you will still want to slowly open it up. over the period of at least 2 weeks. take it slow and only bad things happen fast and all that .....
 
where is Jhardman in all of this? I'd like to see some results! rsman...you're reputation is credible at worst, highly respectable most of the time...just wish I knew 1/2 of what you know and perhaps I could figure things out! Thanks for all the info...
 
Sorry to bring up an old thread but what have the results been for you people who tried it and did RSMAN ever get those photos up,

Thanks Dan
 
Facinating read. I am in the process of building a breeding system and looking at using bio balls, but this coil sounds wonderful.

Would love to see the pics and also more information on what pipe you used for the coil. I am in Minneapolis next week and then SFO after that, so will try and get all that I need vefore returning to the UK.

Shopping list and places to get please folks.

Thanks
Steve
 
Steve, the coils are for nitrification removal of nitrate(without oxygen). Bioballs in a trickle are good for denitrifying the dredded ammonia (these bacteria work best with lots of oxygen). Just thought you might not have caught that. Denitrification is essential, nitrification is a nice to have. Nitrates aren't that dangerous in a fish only system, however, you said something about coral propagation, so probably you want both. If you were already aware, my bad.

Well, mine didn't work. Actually I've built two of them and niether have worked so far. Not sure what I've done wrong, I consider myself fairly cognizant when it comes to following directions, so I have no idea other than it must be beyond me.

Kathy,

Thanks for the remnder. I do have an Aquamedic Nitrate reductor (new word???) but I do not believe that it would cope with the volume of water that I am talking about. I will have a trickle tower of sorts too. That way I can achieve both I hope.

Steve
 
instead of puting bio balls, can you use calcium reactor media? will this have a positive affect? what type of pumps are you talking about to feed these things? maxi jets? would an aqua lifter work? if not, can you show me a pic of this T and valve assembaly? how much tube would i need for my 20 gallon reef tank? for my 75 south american cichlid tank?
