Tej zaum qhov nyuaj tshaj plaws ntawm kev tswj tuav dej (txawm hais tias dej tsis qab ntsev, dej hiav txwv lossis dej hiav txwv) yog tswj kev ua kom tsis txhob muaj algae kev loj hlob.

No mas, cov khoom cia li nthawv cov neeg tsim hluav taws xob yog tias koj ua yuam kev ib yam, xws li muab ntses hla dej, hla ntawm kev hloov dej los yog ua kom lub taub dej hloov cov tshuaj lim dej.

Algae tsis tuaj yeem loj hlob los ntawm tsis muaj dab tsi. Yog lawm, muaj peev xwm ntawm photosynthesis, lawv yeej tau txais lawv lub zog los ntawm lub teeb. Tab sis zoo li txhua yam nroj tsuag, lawv yuav tsum tau txais cov khoom lag luam nyob hauv lawv cov biomass los ntawm lawv cov ib puag ncig ib puag ncig hauv cov qauv ntawm ntau yam as-ham. Hauv lwm lo lus, algae xav tau chiv.

Cov khoom siv tseem ceeb hauv "algae fertilizer" yog ammonia / ammonium, nitrite thiab nitrate. Nitrate yog hom uas nyiam los ntawm cov nroj tsuag feem ntau. Yog li ntawd, tswj cov qis qis ntawm macronutrients, xws li nitrate, yog qhov tseem ceeb rau kev ua kom lub tank tsis muaj algae.

Lub Luag Hauj Lwm Ntawm Cov Ntses Lub Pas Dej Nitrate yog dab tsi?

Vim tias nws yog ib qho tseem ceeb, nitrate tuaj yeem siv tau nrawm dua hauv thaj chaw ib puag ncig. Qhov tseeb, hauv ntau lub ecosystem, nws yog ib qho txwv cov khoom noj kom tsawg. Nitrate yog qhov tseem ceeb rau kev loj hlob thiab rov ua dua ntawm cov nroj tsuag, thiab vim tias nws yog qhov tsawg, nws cov khoom muaj ntau cuam tshuam ncaj qha rau cov khoom lag luam algal. Hauv cov xeeb ceem tsis zoo-cov dej tsis zoo ntawm cov chaw nyob xws li coral reefs, kev loj hlob algal yog heev, muaj kev txwv ntau heev.

Cov ntses tso tsheb hlau luam yog lwm zaj dab neeg, feem ntau yog vim qhov tseeb hais tias cov kab ntses dej muaj kab rov ua dua tshiab muaj kev rov lim dej thiab lim dej dua tshiab. Txawm hais tias cov kuab lom yuav hloov mus rau cov tshuaj muaj kuab lom tsawg tsawg, kev txuam nrog lawv cov khoom siv roj ntsha tau tsim lawv tus kheej teeb meem.

Noj, piv txwv li, lub voj voog nitrogen. Thaum peb pub peb cov ntses, lawv tsim cov khoom lag luam nitrogenous zoo hauv daim ntawv ntawm ammonia. Nitrifying cov kab mob hauv peb lub npe lim roj lom hloov cov ammonia rau nitrite thiab nitrite ua nitrate. Txhua qhov zoo, txoj cai?

Tsis tas! Cov nitrate yuav mus rau qhov twg? Yog tias koj teb tsis tau lo lus nug nrog lej, koj yuav tsum pib sim koj cov dej!

Kev tso siab nitrate nyeem tau sai thiab yooj yim tau siv cov khoom ntsuas zoo, xws li API Nitrate tshiab thiab ntsev dej thoob dej yug ntses kuaj cov khoom siv. Yog tias koj cov qib nitrate siab dua cov saum toj no, hais, 10 lossis 15 ntu ib lab (ppm), koj tau txais qee yam ua.

Cov Kev Phom Sij Ntawm Cov Nitrate Ntau Dhau Los

Muaj tseeb, koj tau raug qhia ntau zaus tias nitrate tsis muaj kev phom sij. Ntau tus ntses yuav tuaj yeem tiv taus qhov kev luv luv txog li 550 ppm. Tus mob ntev ntev, ntawm qhov tod tes, tuaj yeem ua rau muaj kev puas tsuaj, txawm tias nyob rau theem qis qis tshaj qhov cuam tshuam.

Sij hawm dhau sijhawm, tsuas yog 30 ppm, nitrate tuaj yeem cuam tshuam cov kev txhim kho ntawm tes hauv ob qho ntses thiab thiav. Qias plhaw, tsis muaj xim tsis zoo, lub cev tsis muaj zog thiab tsis muaj zog ntawm cov lus teb pub mis yog txhua yam cim ntawm kev ua paug ntawm nitrate.

Cov kws tshaj lij thoob dej feem ntau sib cav hais tias nitrate ntau yuav tsum tsis pub ntau tshaj 20 ppm tab sis muaj ntau yam muaj kev nyab xeeb tuav qis dua 10 ppm.

Tseem, nitrate ntau ntawm tsuas yog qee qhov ntawm ib lab tuaj yeem ua rau kom muaj cov pa dej algal loj. Cov no tuaj yeem tshwm sim xws li planktonic (piv txwv, "dej ntsuab") lossis benthic (piv txwv li, zaj duab xis lossis qeeb qeeb) cov paj ntoo.

Txog thaum lawv dhau los ua pov thawj, lawv twb tau zoo rau lawv txoj kev txhawm chim txhawm rau txhawm rau tawm koj lub pob zeb, cuam tshuam rau koj cov kuab tshuaj dej thiab ua rau koj lub tank feem ntau ntsia thiab tsis zoo.

Muaj tseeb tiag, txoj hauv kev zoo tshaj plaws kom tsis txhob tawm tsam algae hauv cov kev voj voog uas tsis muaj qhov kawg yog kev tiv thaiv nws txoj kev loj hlob dhau los ntawm kev txwv cov khoom noj kom tsawg.

Yuav Ua Li Cas Txo Nitrate hauv Lub Thoob Dej Thoob Ntiaj Teb

Muaj qhov tseem ceeb ob txoj hauv kev uas cov qib nitrate tuaj yeem ua kom qis qis, txawm tias nyob hauv cov chaw muaj tsiaj muaj txiaj ntsig zoo thiab muaj txiaj ntsig. Cov no yog (1) ua kom cov tswv yim nitrate tsawg tsawg thiab (2) txhawb nws kev tshem tawm / uptake.

Kev Siv Me Ntsis Ua Si

Yog lawm, tsawg kawg ntawm peb yuav lob lub raj mis uas nyeem ntawv NITRATE khav thiab hliv nws cov ntsiab lus rau hauv peb cov thoob dej yug ntses. Nitrate tau nkag mus rau hauv peb cov tso tsheb hlau luam ntau txoj hauv kev, xws li hauv dej hloov pauv, tshuaj ntxiv thiab ntses zaub mov.

Thiaj li, ib qho yuav tsum tsuas siv cov dej huv rau kev hloov lossis sab saum toj, nco ntsoov tias txhua yam khoom siv hauv dej tsis muaj nitrate, thiab tom qab ntawd, ua raws qhov loj ntawd: noj koj cov ntses sparingly!

Ua Kev Hloov Ua Dej Hloov

Kev tshem tawm yog yooj yim txaus yog tias koj nqa tus nqi loj, sib pauv dej tas li. Kev hloov dej yog qhov txhaj tshuaj kom pom tseeb, raws li lawv sai thiab tshem tawm cov nitrate los ntawm lub system.

Xav tshem 20 feem pua ntawm cov nitrate hauv dej? Ua ib qho kev hloov 20 feem pua dej; nws ncaj li qhov uas.

Tsis tas li ntawd, kev siv tshuaj lim tawm (xws li Deep Blue Professional nitrate reducer lim media pad) nruab nrab ntawm kev hloov pauv dej tuaj yeem ua rau zoo siab tos txais thaum muaj qhov xwm txheej loj.

Txhim Kho Qhov Refugium

Rau cov neeg uas tsis saib xyuas rau cov haujlwm uas xav tau hauling lub thoob hnyav txog, muaj ib txoj kev xaiv uas tuaj yeem txo qhov kev thov sib pauv dej. Siv cov tshuaj tiv thaiv kab mob cog, tus neeg saib xyuas lub cev tuaj yeem tsim kom muaj cov nitrate ncaj qha los ntawm cov dej los ntawm kev nyob, kev loj hlob ntawm macroalgae.

Kev tshem tawm ntawm cov nitrate (thiab lwm yam khoom noj muaj txiaj ntsig) tshwm sim thaum ntu ntawm cov qoob loo sawv ntsug yog muab thiab muab pov tseg. Txawm hais tias lawv yuav tsum tau nqis peev me me rau kev txhim kho, refugia muab cov kev them nyiaj ntev ntev nyob rau hauv daim ntawv ntawm kev nruam, ze-dag zog thiab tag nrho cov roj nitrate tshem tawm.

Ib tug yuav hais tias lawv muab cov kev nthuav kev nthuav dav tshaj plaws ntawm kev tshem tawm nitrate, nyob rau hauv tias faus cov seaweeds (qee qhov uas tuaj yeem zoo nkauj heev) yog qhov muaj txiaj ntsig txhua yam hauv nws tus kheej.

Siv Microbes

Thaum kawg, ib qho tuaj yeem tswj cov qib nitrate (ntawm no ntxiv los ntawm kev siv roj ntsha) siv ntau hom microbes. Cov kab mob sib txawv no txawm tias yog ua nitrate rau biomass lossis hloov mus rau lwm qhov khoom (piv txwv, cov pa roj nitrogen).

Cov kab lis kev cai nyob tau muaj ntau zuj zus hauv lub lag luam. Cov no suav nrog ob hom aerobic thiab anaerobic. Aerobic cov ntaub ntawv (feem ntau cov kab mob heterotrophic) tuaj yeem siv tshuaj nitrate sai sai tab sis feem ntau yuav tsum "pub" cov pa roj carbon monoxide, xws li ethanol.

Cov ntaub ntawv Anaerobic (xws li cov kab mob nonsulfur ntshav) ua haujlwm qeeb dua tab sis tsis tas yuav muaj cov kuab tshuaj, vim lawv feem ntau nyob tob hauv cov av qis hauv qhov chaw uas muaj cov organic ntau.

Tsis tas li ntawd, tsis zoo li lawv cov aerobic counterparts, anaerobes ua rau tsis muaj kev pheej hmoo ntawm cov xyoob ntoo (feem ntau los ntawm cov pa roj carbon overdosing) uas tuaj yeem ua rau muaj pa oxygen ua kom lub cev puas tsuaj tau.

Feem ntau, nws yuav yog qhov zoo tshaj plaws los pab txhawb ib lub zej zog microbial uas yog qhov ua tau zoo thiab muaj ntau yam sib txawv. Qhov no tuaj yeem koom nrog sib ntxiv ntawm lub txaj xuab zeb, siv cov kab mob ua haujlwm thiab cov kab mob ntxiv / cov zaub mov tsis tu ncua.

Txawm li cas los xij koj xaiv los tswj cov nitrate, ib qho yog qhov tseeb: kom muaj cov tsiaj muaj kev noj qab haus huv nyob hauv lub thawv dej uas tsis muaj algae, nws yuav tsum tau tswj hwm nruj.

Los ntawm kev ua raws li cov kev hloov dej nruj, siv cov dej lim huv nkaus xwb, ntxiv cov ntxaij lim dej zoo tshuaj, txhim kho qhov tsis muaj zog thiab txhawb kev loj hlob ntawm cov microbes tau txais txiaj ntsig, koj tsis tas yuav muaj kev tawm tsam nrog kev ua kom muaj kab mob nitrate!
