Izinga le-pH emanzini asemanzini anosawoti yilokhu okukhathazeka njalo emanzini amaningi asemanzini. Nakuba abantu abahlala ohlelweni lwezinhlanzi kuphela abakwazi ukubekezelela izinga eliphakeme kakhulu lamazinga e-pH ngezikhathi ezithile ngaphandle kokulimala okukhulu, abahlali be- tank reef baxhomeke kakhulu kwizinga le-pH elingaphakathi uhlangothi olufanele nje ukuze basinde, bangabi yedwa phumelela. Izinga le-pH elamukelekile ohlelweni oluyisisekelo lwamanzi anosawoti luphakathi kuka-7.6 no-8.4, kepha amathangi angama-reef azwela kakhulu, ngakho-ke adinga ukugcinwa ekugcineni okuphezulu kwezinga le-pH, 8.0 kuya ku-8.4.
Ukuze ulawule noma ulungise i-pH, umuntu kufanele aqale aqonde ukuthi kuyini. Ukuze sigcine lolu daba luyisisekelo esiyisisekelo, ngeke singene ekuxhumaneni kwama-ion ezingeni lezamakhemikhali ezenza konke kwenzeke. Lapha sizoxoxa ngalokho okwenzekayo ezingeni le-layman.
I-pH isichazwe kalula
i-pH (amandla ka-Hydrogen) nje umlinganiso we-acidity noma i-alkalinity yesisombululo. I-pH ye-7 ibhekwa "engathathi hlangothi," noma i-asidi noma i-alkaline, kuyilapho i-pH engaphezulu kwe-7 ingu-alkali noma "isisekelo," futhi ngaphansi kwe-7 iyasebenza.
Indlela evamile ye-pH ohlelweni lwamanzi anosawoti iyancipha, noma i-acidic eyengeziwe, etholakala ekungezeni ama-acids emanzini. Lawa ma-acids avela emithonjeni eminingana, okuyinhloko yiyo: (1) i- carbon dioxide eyengeziwe (CO2) okuvela ekuphefumuleni okubangelwa ukungabi nhlobo kokushintshaniswa kwegesi, (2) i-nitric acid kusuka ekufakweni kwe-biological (nitrification), kanye (3) nama-acids e-organic izidakamizwa zamanzi.
Yiqiniso, ukuphefumula kanye nemfucumfucu yemvelo kunengxenye yemvelo yolwandle.
Kodwa-ke, isizathu sokuthi amanzi asolwandle asishintshi ukuthi amanzi aqukethe amakhemikhali ambalwa, njenge-bicarbonate, i-calcium, i-carbonate, i-borate, ne-hydroxide, konke okusebenza njengama-"buffers" emvelo okwehlisa ukwehla kwepH.
Ngakho-ke ukuphi ukungena kokungena kuvela kulokho konke lokhu? Isilinganiso lapho isisombululo sigcina khona i-pH uma i-asidi yengezwa kuthiwa yi-"alkalinity" yesisombululo.
Amagama afanayo asetshenziselwa ukubhekisela emanzini yi-carbonate noma i-calcium nobunzima, kanye ne-German efanayo, KH noma i-DKH. Inani "lezinhlanzi" emanzini olwandle lenza ukuthi i-alkalinity ibe yindawo.
Uma i-pH ohlelweni lwamanzi anosawoti eqala ukuwa, kuyisibonakaliso sokuthi ama-buffers ayaphela, futhi ukwanda kwe-acidity kudinga ukulungiswa.
Izindlela Zokulungisa Izixazululo ze-pH
- Izindlela zokulungisa ngokushesha ukuphakamisa i-pH kufanele zengeze i-bicarbonate ye-soda (i-baking soda), noma umkhiqizo wokulungiswa kwe-pH.
- Ukunciphisa i-pH ephezulu, izixazululo zokulungiswa okusheshayo kufanele wengeze uviniga noma ijusi lemonsi, noma umkhiqizo wokunciphisa i-pH.
- Indlela evamile eyamukelekile "evivinyayo neyiqiniso" yokuzinzisa i-pH iseyenzayo izinguquko zamanzi ezivamile. Lokhu akugcini nje ngokuvuselela izitshalo zemvelo kodwa futhi kubuyiselwa amaminerali okulandelela emanzini e-aquarium. Yiqiniso, ukunciphisa izimbangela zokudonsa ku-pH kuhlale kuhlakaniphile. Ukukhipha konke ukudla okungafakiwe nokudoba inhlanzi kusuka ethandeni njalo kuzohamba ngendlela ende ekuvimbeleni ukwehla kwe-pH.
- Sebenzisa i-doser elula ukufaka ngokuzenzekelayo ama-buffers kanye ne-calcium, i-iodine, ezinye izakhi zokulandelela ezibalulekile, nezithako.
- Nakuba kuyabiza kakhulu, ukufaka isisitoreji se-calcium kunganikeza isisombululo esingenasisindo sokulawula izinkinga ezinkulu ze-pH ne-alkalinity.
Khumbula ukuthi noma yikuphi ukuguqulwa okukhulu kwezinga le-pH kuthegi lakho kufanele kwenziwe kancane. Ukuphakamisa i-pH kusuka ku-7.4 kuya kwezingu-8.4 ngendaba embalwa imizuzu kungenza ukuthi i-pH ishaqele cishe kunoma yiliphi inhlanzi yamanzi yasawoti (kanye nama-invertebrates) abangela ukufa. Uma wenza izinguquko ezinkulu, yenze kancane kancane njengoba ungathanda uma uvumelanisa abasha abafika e-tank yakho.
Amanzi okusawoti, ngaphandle kwamathonya angaphandle, azogcina i-pH eqhubekayo. Uma kunjalo, kungani i-pH e-aquarium yakho yamanzi yasawoti ishintshe, ngokuvamile iyancipha? Ezimweni eziningi, ukwehla kwe-pH kungenxa ye-asidi eyenziwa ngokukhiqizwa nokunciphisa i-ammonia. I-ammonia idalwa yimfuyo e-tank njengoba idla ukudla futhi ikhiqize imfucuza (ikakhulukazi icala le-detritus) elishayo. Ukudla okungavumelekile phansi kwe-tank kuveza futhi i-ammonia njengoba idiliza.
Kuyafana nanoma yikuphi ukugxeka okufile okusele ethanini.
Uhlelo olujwayelekile lokulondolozwa kwamathangi olususa inhlanzi yezinhlanzi nokudla okungahambisani nokushintshwa kwamanzi ngamanzi ngamanzi amasawoti amasha ngokuvamile kuvame ukugcina i-pH emanzini akho ngesikhathi esifanele bese wenza ushintsho lwe-pH into eyedlule.
