Wasn't sure if the systems with the big tank were RO
I'm putting together a brackish system now (GSP) and future plans for a 29g SW
so I'm planning ahead. Plus the buffers in my water supply are tough (GH
of 120), so I was going test doing a 60/40 of tap/RO
for my fresh tanks. My pH is 7.8 at best and the Cardinal Tetras are max 7.4 pH from everything I could find on them.
