Hejsa
Jeg har kæmpet med at få hævet min PH værdi ved udluftning uden held, jeg er så blevet anbefalet at tilføre "kalkwasser" og ville i den forbindelse høre jer om hvordan i tilsætter dette, bruger i en reaktor til det eller er det bare manuelt.
Jeg har læst denne artikel http://www.reefscapes.net/articles/bree ... asser.html
som omhandler "kalkwasser" hvor det anbefales at anvende eddike i den blanding "Kalkwasser" som man anvender, er der nogen her fra som anvender denne løsning?
for lav ph værdi
Citat:
Dissolving the Kalk powder in the Vinegar first will accomplish several very good things.
First, it will get more Calcium ions (Ca++) into the solution because you are dissolving the Ca(OH)2 in an acid instead of water, and forming Calcium Acetate, which exists as a dissociated equilibrium of free Calcium ions and Acetate ions.
Second, the Acetic Acid (Vinegar) provides an equivalent of all the CO2 you need to avoid precipitating the newly-added Calcium ions as useless white Calcium Carbonate powder.
Third, after all the cool Calcium ion chemistry is over, the leftover Acetate ions from the broken-down Vinegar leaves you with free organic Carbon in the water that feeds the bacteria in your tank so that it converts more poisonous Nitrates to NO2 gas (a very good thing).
Adding Vinegar in Kalkwasser is one of the few win-win situations for reefers -- it has a great up side and I've yet to encounter a down side to doing it. I don't know why so few reefers do it -- lack of understanding of the chemistry behind it maybe -- but a lot more are starting now that some respected reef writers have discovered it and have recommended it and even written up detailed instructions for it.
Citat slut.
Ville det være bedre at prøve med et færdig produkt fra f.eks sera som hæver PH værdien langsomt naturligvis?

Jeg skal jo anvende Balling, og iflg. hobbyriff, så skal jeg alligevel tilsætte calcium hydroxid for at opretholde PH som falder når man bruger RO vand til at efterfylde med pga. fordampning.
De skriver således om blanding af det:
To avoid this, try mixing and adding your Kalkwasser like this: pour 15ml of 5% Acetic Acid (or ordinary Distilled White Vinegar from the grocery store -- same thing) into a 1 liter (1 quart) container. Dissolve 1/2 teaspoon of lab-grade Ca(OH)2 (or commercial Kalkwasser mix) in the Acetic Acid, and then dilute to 1 liter (1 quart) volume with either RO/DI water, or even tank water.
Men hvis jeg anvender balling og skal anvende sådan en her: Ratz Calciumhydroxid-Reaktor Typ 110 også så er det da lidt voldsomt.

ja men det er jo en kalkreaktor og ikke en calciumhydroxid reaktor
Så vidt jeg har kunnet finde frem til så skal jeg bruge den ratz som jeg omtalte tidligere, eller en cola flaske og så gøre det manuelt.
Det her er hvad Ratz skriver på deres side:
Calcium-hydroxyd reactor type 110
Art.No.: 222 227
Technical data
Aquarium from: 50 up to 530 gal ( 200 - 2000 L )
Pipe : 4,33 inch ( 11 cm )
Total high: 26,2 inch ( 66,5 cm )
Capacity about: 1,05 gal ( 4 L )
Engine power: 5 Watt
max.: 7,5 Psi ( 0,5 bar )
The calcium-hydroxyd reactor is from the new generation and developed by Ratz Aquarientechnik. Many aquarium people work with calciumhdroxyd to the old method, into a bottle. This is a old system. When you open the bottle the oxygen reacts with the air. The reactor from Ratz Aquarientchnik works 10 to 15 days, by 1,05 gal.( 4 l ) per day. This is a revolutionary system, and economical. Work of the system: You fill the reactor with 40 - 50 gr. Calciumhydroxyd, and cosed the cover. Then you join the water tube with a dosing-pump or centrifugal pump. You fill the reactor with osmosis water, "not seawater". The regulate you make with a electronic timer. About all exchange mixes the water with Calciumhydroxyd. In the dormancy falls the Calciumhydroxyd down. The exchange you can all 30 minutes repeat. The exchange water quantity is a aproximate 0,25 gal, ( 1 l ) and this you can exchange into about 15 - 30 minute. If you work with a dosing pump, you can triplethe exchange. By the way, when you need plenty of calcium you can work paralel with a Ratz Calcium-reactor.
Den kan jeg da ikke bare erstatte med en kalkreaktor eller hvad?

De ting har altså ikke noget med hinanden at gøre.
Jeg har fyldt osmose vand på i flere år, og har aldrig haft problemmer i den retning. Hvor har du fået den ide om at det er osmosevandet der gør det??
Hvad vil du fylde i den kalkmikser som kun hæver Ph og ikke bringer nogle af de andre værdier ud af balance??

citat fra http://www.drhelm.com/aquarium/chemistry.html:
Ways to lower pH
• Filtering water over peat
• Add bogwood to the tank
• Inject carbon dioxide CO2
• Use a commercial acid buffer
• Water changes with softened water or RO (Reverse Osmosis) water
Ways to raise the pH
• Aerate the water, driving off the carbon dioxide (CO2)
• Filter over coral or limestone
• Add rocks containing limestone to the tank or use a coral sand substrate
• Use a commercial alkaline buffer
Citat slut
Calcium hydroxid ændre på PH, CA og Mg iflg det link som er postet tidligere i denne tråd.
Men jeg kan da under alle omstædigheder ikke tilsætte kalk fra en reaktor samtidig med at jeg anvender balling, så vil KH jo stige til alt for høje værdier.
