My Inca's spawned in Ph 5.9, so far I have been maintaining the Ph 5.9 for the fry. The first batch that was swimmers on January 28 is still at 5.9. Do I need to keep them at 5.9? Or can I just start weaning them off this water and have no sex ratio problems. What are the most important parameters to maintain to get an even split on the sex ratio? I am mixing RO, a little tap water and peat treated water to get the 5.9.
