Biowheels create nitrates 24 hours a day. Dirty filter pads do as well. Plan on
rinsing them well every 3 or 4 days if you want to stay with that system. My 29g doesn't have any type of filter pad, wheel, sock .. nothing. The water is crystal clear and people are surprised by this. Particulates trapped in any type of pad will rot as they break down and nitrates have nowhere to go but up. http://www.melevsreef.com/reducing_nitrates.html Marc Phil O'Connor wrote: My Emperor filter is not a canister, but a hang-on-back powerfilter with biowheels. Admittedly, I dont change the filter pads often enough, and I'm sure they become nitrate booms. Thats an area I can improve. And I will repopulate the janitorial crew. Good suggestions. But I'm confused about your remark that I dont have enough filtration to remove nutrients. My biological filter (be it the biowheels, liverock, or both) is sufficent enough to keep ammonia and nitrate to zero. That just leaves denitrification. And all I can do there is water changes, which is very slow, and cant elimiate nitrates altogether. I cant put in a DSB at this point. I could scale up my liverock, but the liverock in my nano reef fails to denitrify at all, so I'm skeptical that it would be successful in my big tank. Or do you mean that, for instance, a janitorial crew is part of a 'filter' to remove nutrients? That I can understand. So at this point, my plan of attack is more frequent vaccuming/water changes (I get lazy *blush*), more frequent filter pad replacement, scale up janitorial crew. Other than that, I dont believe I'm understanding your objections to my Emperor filter. And do see any value in putting more live rock in? Like I say, I've had no success getting liverock to denitrify in my other tank, so I dont know how to ensure that will work. Thanks again, I really appreciate the help.

Crush Coral Emperor Filter Janitoral Crew Other - Food get trap in substrate which will decay - While being decay, it will release nutrient. No Janitoral crew to pick up any trash [sense of speaking] or scavaging Double check your RO unit again with a TDS to see what the product water rated at. Since you did not indicate any phospate so I am not to sure if RO may contribute to it. If I can remember from your previous post, you have like over 40ppm nitrate. This will contribute food for algae. I should have gave this link earlier but since Marc provide now. Try this link - http://reefkeeping.com/issues/2002-12/nftt/index.htm Try putting some Mexican Turbo snail and hopefully your Trigger will not make a meal out of it. During that meantime, you will need to manual prume and siphon out. General speaking, I do not see your tank have much filter to remove excess nutrient. But I do see as mechanical type filter due to your canister to remove waste only and not really effecient enough. Your nitrate is your obvious biggest problem. Canister / crush coral / decaying food are your contributor. Your Protein Skimmer will not effeciently enough to remove it. PS can not remove anything if it get stuck in your substrate until it release and floating about in your current for it to remove it. That maybe the reason why your subtrate and rock have algae.

Marc,
So how do you maintain crystal clear water with no mechanical filtration? During vaccuming and water changes, lots of particulates get kicked up, and I cringe until my mechanical filter clears the water again. What confuses me is, yes, biowheels create nitrates 24/7, but so does any biological filter, no? Thats what its there for. And you need that. Or is the issue that live rock performs more efficiently as a biofilter, and produces fewer nitrates? Or are you saying biowheels sustain nitrate production even when the cycle is not being fed with DOCs, whereas liverock wont. I like how you've converted a trickle filter into a sump. Actually, you have me thinking very seriously about installing a sump/refugium, and employing DSB and macroalgae for denitrification. I'm very nervous about yanking my biowheels, since thats my established biofilter. I may consider slowly ramping up the liverock until thats active, and then axing the biowheels. Do I need strong lighting to use liverock as my primary biofilter? I have only 30w now. In anycase, that will be a slow migration. Meantime, I think I'd like to take on a sump and get denitrification happening. Thanks, Phil Marc Levenson wrote in : Biowheels create nitrates 24 hours a day. Dirty filter pads do as well.

Hi Phil,
The water remains crystal clear as long as I keep my hands out of the tank. The oils on my skin affect water tension, as does a water change or new top off water, as does feeding the tank. The stuff that blows around in the tank ends up being food for something, so I have no reason to trap and remove it. All that is in there I put there, including daily food. The clean up crew, the microfauna and the livestock help eat up what is edible (on some level). During a water change and/or siphoning of the gravel, the water will get dirty, but it clears up within an hour or two. If you have corals, that is typically the time they'll feed on the floating detritus. Some guys on ReefCentral.com even intentionally blow all the stuff that landed in the sump, getting it back into the water so their livestock can have another chance and consuming it. The skimmer will pull out what is in the water as well. The biological filter can only deal with a specific amount of pollutants, and once they get too high LR & LS can't keep up. By getting those levels down, success is attainable. I did convert a trickle filter into a sump, and used it for about 6 weeks until I built a brand new sump that had room and volume. It makes caring for my 55g a real breeze. LR doesn't depend on lighting, that I'm aware of. I do believe a DSB does, because I've seen bubbles formed on the substrate during the day time (nitrates coverted to nitrogen gas bubbles) which rise and pop. I've never noticed this occuring during lights out. You can make the conversion slowly. As soon as you have the sump and refugium in place, that would be the perfect time to pull out the biowheels. You can put additional LR in the sump if you don't want it in the display tank. Marc Phil wrote: Marc, So how do you maintain crystal clear water with no mechanical filtration?

Or are you saying biowheels sustain nitrate production even when the cycle is not being fed with DOCs, whereas liverock wont. Bio-wheels, bio-balls, canisters, etc. are great at convertin the Amonnia to nitrite and nitrites to nitrates, but due to the areobic bacteria that is growing on the media. To convert the nitrates to a harmless gas you need anoxic (low oxygen ) zones for anaerobic bacteria to colonize. These bacteria (anaerobic) colonize in deep sand beds and deep within the live rock. Running filrtermedia (bio-wheels) and liverock/DSB just causes compitition within the 2 types of bacteria, and none of them get up to their full potential of doing what they are meant to do.

You can inspect how your filter work.

[/snip] BiosFIlter job is to trap prolllutant or particle that can be stuck in those coarse hole. That the reason biosfilter is 24/7 nitrate factory. Bacterial convert to nitrate but nothing will convert to nitrogen gas to be less toxic and be release. It will stay there until you either remove it or it get decay and release itself. Your whole Marine tank is consider a filter. You need everyone including bacteria to do their part. [snip] I like how you've converted a trickle filter into a sump.

Normal light will be ok for macro algae. CapFusion,... |

Maybe the word "competition" maybe not the word to use. Those bacteria that convert to nitrate IS much more effecient depending where they live. In trickle sump type, they live in open air where water pass-through but in submerge like in a gravel / crush coral it will not that effecient but enough that ananerobic bacteria from DSB can not catch up. Maybe this general idea will help. CapFusion,... Maybe I'm misunderstanding what 'efficient' means. Is efficient BAD? (meaning higher nitrate production per DOC input) I guess that makes sense. Therefore, filter media, being more efficient, is undesirable. Do I have that right? Phil (still me, just posting from my work) |

I believe you using "Fresh Water" method on how to clean / filter your Fresh Water Tank. But everything I see in marine tank instruction and/or sales always includes all three filters: mechnical, chemical, bio. Although I can understand how some may adopt an alternate philosophy do to away with mechanical (as explained here), its not actually considered 'wrong' for marine tanks, is it? Its still the conventional wisdom for marine, no? And we havent even talked about chemical. I see Marc has done away with that too. Whats the theory behind that? Chemical is just for odor elimination, isnt it? So there's no danger without it, just smells. So, Marc, are you living with tank odors, or does your system handle that naturally too? Remove the Bio-ball or media where it house very effecient bacteria where it live and convert to nitrate. You will need to slowly convert from trickle to DSB sump or Refugium. Normal light will be ok for macro algae. Does DSB house ALL types of necessary bacteria? So it can stand alone as biofilter? Or is LR needed with it? I gotta say, I've been at this over 2 years now, and research constantly, but every now and then, I get input that reduces me back to feeling like I know nothing :-) |
