Hello, I will have those P. ‘deissneri’ on friday. The first thing I will do is picture of them:) About conductivity, I suspect that my RO prefilter is too old ( or maybe even membrane) so I will need to replace them soon. About water, I use water from my 625L tank to water changes in small tanks with paros, I think that parameters in big tank with big sump filter are rather good and constans.
