Hvorfor tilsætter i Ozon ?
Hvorfor tilsætte i Ozon og hvad gør udslaget for at i tilsætter det.
Hvor længe kører i så med det. / hele tiden / 1 gang pr. mdr. / 1 gang pr. uge / kun om natten.
Er lidt i tvil om jeg skal forsætte med Ozon eller ej.
Hvilken Effekter og side effekter har ozonen helt nølagtig

Re: Hvorfor tilsætter i Ozon ?
Taget fra en artikel på nettet:
Ozone:
Sometimes called the "purest form of oxygen", ozone, O3 is a highly unstable tri-atomic molecule. It's the smell that's so fresh after an electric storm, the crispness in the air in and around large electric motors; it can be a boon to you in "burning" up organics and microbes, raising pH, dissolved oxygen and Redox, and most importantly, boosting the efficiency of your protein skimmer.
How It's Made: By an ozonizer, through a process called ozonolysis; okay, sorry to be so smart-alecky. Older, low-production units utilize a germicidal lamp, such as those in U.V. sterilizers. The higher yield, more modern models use a corona discharge (electrical) method of making ozone.
How It's Applied: The optimal application of ozone is through your skimmer, with the water's discharge back to a sump (usually a filter) for mixing, out-gassing, and chemical filtration before return to the main system.
Dedicated air: feeder systems to skimmers come in two formats, pressurized air and venturi. With the latter air is drawn in by partial vacuum, the first involves an air pump. What type? A strong, quiet, dedicated one; that is one that is only operating the skimmer. This is necessary to avoid "adjustment headaches", a condition you will get if you chintz and try to gang other outlets with your not-so-dedicated skimmer air pump.
Whether you have a pumped air or venturi delivery, you should utilize a good check valve to prevent "back-siphoning" through capillation, and ozone resistant tubing. If you are or become a total fanatic, you can even increase your ozone production efficiency with an air dryer. Let me hasten to add that, yes, ozonizers work fine without air-dryers (but better in low humidity air), and double-yes, protein skimmers work fine without ozonizers (though not as "efficiently").
Ozone Dangers: Numerous authors cite the need for carbon filtration, venting to prevent ozone poisoning of livestock, and even hobbyists (!). These fears are largely unfounded. Though I would not directly introduce ozone into a system, the little that intended units produce is dissipated quickly when utilized in a skimmer. The worst that does occur with small ozone generators is increased corrosion of "rubber" materials in your system; well worth the many benefits. You, your fishes and house will not burn up or down, I promise.
My Overall Ozone Opinion: The chemical degradation of large organic molecules, responsible for off-color, turbidity, low oxygen and some toxicities by ozone make it's small start-up and operational costs pale. If you're even vaguely considering an investment in any sort of meter, doser, denitrator, ultraviolet sterilizer... STOP, do not proceed to go; buy and use a small ozonizer in conjunction with your skimmer first. Almost all public aquaria utilize ozone with theirs; you should to.

Re: Hvorfor tilsætter i Ozon ?
Jeg plejede at køre med det konstant, men efter at jeg startede på Prodibio stoppede jeg. Nu bruger jeg det ind i mellem i et døgns tid til at klare vandet, selvom det egentlig ikke hjælper, da mit vand er meget klart alligevel.

Jeg har forsøgt at køre med ozon, men min skummer dør totalt, der kommer mindre skum end uden. Hvorfor har jeg ingen ide om.

Re: Hvorfor tilsætter i Ozon ?
Kunne det ikke tænkes ( ved det ikke ) at luft tilførelsen ikke er stor nok. Jeg har selv en c100 ozonisator og når jeg har haft den skilt af og renset, er luft hullet ( gennemstrømningen )uhyggelig smalt. Har du prøvet at sætte en T stykke på, så din skummer kan både trække Alm. luft og luft fra ozon.Carsten skrev:pedersen skrev:Det har ham fra "Reefkeeping" derimod (de er linket tidligere i tråden) - det er en glimrende (omend noget lang) artikelserie.

Ved ikke om det hjælper men jeg kan se det samme på min skummer, at den skummer meget mindre og der kommer færre bobler i selve skummeren.
Jeg vil selv prøve med et sådant T stykke for at tilføre så meget luft som den nu har brug for.

Re: Hvorfor tilsætter i Ozon ?
Vedr. mindsket effektivitet i skummeren, så er det noget mange oplever (prøv blot at søge på reefcentral). Der er flere forklaringer, men en af dem er at det skyldes, at man tilsætter for meget ozon. Er målet alene at optimere skummerens ydeevne (og dermed ikke at hæve f.eks. Redox), skal der faktisk meget små doseringer til - ellers risikerer man det modsatte resultat. Anvendelse af meget små mængder betyder også, at man ikke (som det ellers oftest anbefales) behøver at køre vandet igennem aktivt kul bagefter og ligeledes behøver man ikke en redox-styring.
Det man søger at opnå er såkaldt microflocculation, hvor affaldsstofferne binder sig nemmere, og i højere grad, til vandboblerne i skummeren.
For høj ozon-dosering er dog ikke den forklaring der nævnes i artiklen. Her er afsnittet hvor han kommenterer det (det skal nævnes, at han grundlæggende ikke er positiv overfor ideen med ozon):
Skimming is a complex process that has many subtleties. The previous sections have discussed how ozonation modifies organic molecules , and we can then extrapolate how those processes impact skimming. Years ago it was widely claimed that ozone use increased skimming, and I claimed then that I didn't see how that could happen directly. Most organic compounds likely to be found in significant quantities in a reef aquarium will become more polar and likely less skimmable after it reacts with ozone. Figure 3, for example, shows how oleic acid (readily skimmed) gets converted into more polar compounds that will not be so readily skimmed as they will not be as strongly attracted to an air water interface.
A small portion of organic molecules in reef aquarium water may become more skimmable if, for example, they become more hydrophobic after reaction with ozone. They may also become more skimmable if they were totally hydrophobic before ozone and were transformed into molecules with polar and nonpolar parts (called amphiphilic) which more readily absorb onto an air water interface and are skimmed out.
Are there other ways that skimming might be increased besides these two processes? I hypothesized in a previous article that it was due to the growth of bacteria (either in the water itself, or bound to surfaces), and possibly also the release of new organic molecules as they grew, that caused the effects some aquarists observed.
It seems as if the tide of opinion has turned, however, and most aquarists now claim that the amount of skimmate is reduced significantly when using ozone. Many claim that the collection of skimmate has nearly stopped in their aquaria when starting ozone. Why the difference compared to past opinion? That's hard to say, and may depend on the types and qualities of the skimmers available now compared to years ago, as well as changes in other husbandry practices. In any case, the overriding experience of many aquarists today is that skimming is reduced, and the presumed reason is that the organics are being made chemically less skimmable by ozone. The remaining organics would then be removed more by bacterial processes than before the initiation of ozone in the same aquarium

Re: Hvorfor tilsætter i Ozon ?
Jeg glemte: hvis skummerens effektivitet således mindskes ved tilførsel af ozon, vil min anbefaling derfor være at reducere doseringen (der skal være meget lavere end hvis man f.eks. går efter høj Redox) indtil skummerens output øges - men det er og bliver på "trial and error basis", da der ikke er tale om en eksakt videnskab (specielt ikke når man arbejder i så lille skala som vi i akvarie-hobbyen gør)

Re: Hvorfor tilsætter i Ozon ?
Ja så er den teori jo ligesom skrinlagt carsten.
prøvede idag og sætte en T stykke på mit, det gav en del mere ilt i skummeren end uden.
Dvs. mit har fået for lidt luft i indtaget ( selv om jeg sagtens kan justere den til at skumme )
Men når jeg helt fjerner Slangen til luft indtaget, så går min skummer fuldstændig amok, og skummer for vildt.
Så pt. skal jeg kører uden Slange overhovdet. eller skal jeg kører med Ozon og lade skummeren skumme som den plejer.
