Our conductivity is routinely between 500-700 and we don't have an issue with this.


Hope this helps,

Is anyone familiar with (what looks as) fast growing epthelium on upper gill covers? 
We do'nt have any problem with egg production but it may cause some stress on breathing capacity? 

see picture: 

could anyone reconfirm this could be caused by conductivity? 

system: Zebtec  (http://www.tecniplast.it/_assets/products/CAT012_ING_Internet.PDF) <http://www.tecniplast.it/_assets/products/CAT012_ING_Internet.PDF> 

pH= 7.5 
Conductivity= 500 µS 
Temperature= 27,5 °C 

Conductivity and pH are automatically adjusted with Seesalt and Sodiumbicarbonate. 

Thanks in advance,
