Laagste PH voor roggen

door Sjonson » di 28 jul 2015, 09:01

Ik heb mijn cichliden verkocht en ben me nu aan het orienteren voor een zwart water biotoop. Dat betekend heel zacht en zuur water.
Nu wil ik mijn Scobina behouden en ik wil weten wat de laagst mogelijke PH is waar je roggen op kan houden?

Rond de 6 kan meestal wel, als het maar stabiel is. Met name een sprong omhoog geeft problemen bij roggen.

Lage pH is vaak instabieler, o.a. omdat je verder van het verzadigingspunt afzit. Grote verversingen zijn ook lastig, gezien de pH waarde van water uit de kraan.

Hoe laag wil je gaan?

Ik wil aan de ondergrens van 6 bovengrens van 5. Dus rond de 5,9 ofzo.

Verversen zal gebeuren met voorbereidwater, dus de schommelingen zullen niet meer zijn dan bij normale verversingen vanuit de kraan.

Lijkt me geen probleem. Sterker nog in het wild zitten scobina's waarschijnlijk ook in een pH tussen de 6 en 7. Hoe hoog is de waarde nu?
