Thanks Peter, I just saw you best wishes now.

Sorry that I have been absent for a while from the forum,( even if had had often the plaisure to reed all of you ), but sometime the time dont belong to me and all the hobby have to pass after others things more important (familly and work), even my golf handicap is suffering ...
My new filtration ,with the nexus, works really well and all my koļ are growing in very good conditions. I had to give 5 of them to a friend because my pond is only 3000 gallon and the average lenght of the 12 remaining is now 43 cm.
I ll try to be more present on the forum and wish you all the best.
Marco
