Ho boloka pH ea letamo la hau ho bohlokoa ho netefatsa polokeho ea metsi le boiketlo ha u ntse u sesa.Haeba u leka metsi a letamo la hau mme u fumana hore pH e phahame haholo, ho na le litsela tse 'maloa tse potlakileng le tse sebetsang tsa ho theola pH.Mona ke mekhoa e 5 ea ho theola pH ea letamo la hau kapele:

     1. Sebelisa hydrochloric acid:Hydrochloric acid, e tsejoang hape e le muriatic acid, ke tharollo e matla, e sebetsang ka potlako e theolang pH letamong la hau la ho sesa.Kamehla latela litaelo tsa moetsi le mehato ea tšireletso ha u sebelisa k'hemik'hale ena.Eketsa palo e khothalletsoang ea muriatic acid metsing a letamo 'me ue lumelle ho potoloha lihora tse' maloa, ebe u hlahloba pH hape.

     2. Eketsa sodium Bisulfate:Sodium bisulfate, eo hape e tsejoang e le asiti e omileng, ke khetho e 'ngoe e tsebahalang ea ho theola pH ea letamo la hau la ho sesa.Sesebediswa sena sa granular se ka eketswa ka kotloloho metsing mme se tla theola pH kapele.Hape, etsa bonnete ba hore u latela litaelo tsa dosing ka hloko ho qoba ho fetelletsa metsi.

     3. Sebelisa carbon dioxide:Carbon dioxide e ka kenngoa ka ho toba ka metsing ho theola pH ea letamo la hau.Mokhoa ona o atisa ho sebelisoa matamong a khoebo 'me o hloka lisebelisoa tse khethehileng.Haeba u na le letamo le leholo kapa u batla khetho e tsitsitseng haholoanyane, nahana ka ho sebelisa CO2 ho fetola pH kapele.

     4. Sebelisa pH reducer:Ho na le lik'hamphani tse fokotsang pH tse etselitsoeng matamo ka ho khetheha.Lihlahisoa tsena li bonolo ho li sebelisa 'me li ka fokotsa pH kapele ntle le tlhoko ea ho lekanya le ho sebetsana le asiti e teteaneng.Latela litaelo tsa leibole ea sehlahisoa ho fumana liphetho tse ntle.

     5. Eketsa moea:Ho eketsa aeration ka letamong la hau ho thusa ho theola pH ka tlhaho.Sena se ka finyelloa ka ho tsamaisa pompo ea letamo le tsamaiso ea ho hloekisa, ho sebelisa mohloli oa seliba kapa phororo ea metsi, kapa feela ho tsitsisa metsi ka borashe ba letamo.Ka ho eketsa oksijene ka metsing, carbon dioxide e tla lokolloa, e theole pH.

Ho boloka pH e nepahetseng ka letamong la hau ho bohlokoa ho boiphihlelo bo bolokehileng le bo monate ba ho sesa.Kamehla hopola ho hlahloba metsi ka mor'a ho etsa liphetoho 'me u buisane le setsebi haeba u sa tsebe hantle hore na ke eng e molemo ka ho fetisisa bakeng sa letamo la hau.
