Update...
cardinia tank now has blue shadow and assorted tigers and crs-cbs
maintaining 120 tds
temp 70-72
neo tanks have had a couple dropped berried females now raising 50 or so shrimplets in the mesh breeder
Question though...
how high should the tds be over the norm before doing a water change?
i Mara a mistake when adding 25 shrimplets to my nursery tank from the mesh breeder tank without drip acclimating them and lost all of them overnight.!
i guess the water parameters weren’t close enough. What a bad mistake that was but lesson learned
