Nerites with CO2 injection

I was thinking about getting some nerites from planet inverts. I've heard that their shells melt with co2. Is this true? I have a co2 induced pH of 6.4.

How do you think zebra nerites would fare in my tank? Do you think olive nerites would be better?

I will suggest to add some calcium to it.
I think CO2 is not the culprit, is the low ph water.

Maybe others have more experience with snails and their low ph. I have some in acidic tanks and if I feed them calcium they seem to be okay.

Regards,
Pedro

I have extremely soft water out of the tap, so I do dose calcium for the plants.


I should have phrased it better. I've heard their shells melt in acidic conditions, like those induced by co2 injection.

no nerites shell wont deteriorate if you are using Co2

its the absence of calcium and extremely low pH that do it,
if the snail is healthy and their is a good amount of calcium in the water the snail should be able to repair and maintain its shell

I believe there is a positive coralation between shell deterioration and the amount of carbonic acid in the water. I have been keeping many olive nerites and have noticed shell corrosion in my Co2 aquarium and no corrosion in my olive nerite holding tank. Both aquariums have tap water that are 7.6 ph and 5kh. My tank with CO2 is 6.4 ph which gives me apprx. 30ppm - 60ppm of CO2.

Considering this is the only variable that changes my water parameters I think I can conlcude CO2 does or aids in corroding nerite shells.

One thing I have not tried is putting nerites in an aquarium with say a ph of 8.4 and injecting CO2 to a point where the water does not enter into the acidic continuum.

If you can run this experiment than CO2 may have nothing to do with corrosion but be an interviening variable that my help achieve the acidic conditions needed for corrosion to occur.

Peace,

From what I've read, I beleive the problem to be co2-induced low pH, and not co2 on it's own. I believe this to be supported by reports of people with naturally acidic water with no co2 injection experiencing shell deterioration.

We often try to get people to separate the idea of TDS-controlled pH and co2-induced pH, so that they don't worry about pH effects on fish as a result of co2-induced low pH. However, in this case, low pH is low pH, regardless of the cause.

A two tank experiment would give you very good information. One tank, like you said, with naturally high pH dropped down by co2 and still above neutral.

The second tank, naturally low pH with no co2.
