I am new to keeping shrimp. I have two tanks, both planted low-tech:
Tank 1: 10G, inert substrate (torpedo beach), pH 6.5, KH 0, GH 6, TDS 175, temp ~74
Tank 2: 2.6G, amazonia AS, pH 6.0 or less, KH 0, GH 6, TDS 150, temp ~74
I have breeding RCS in the 10g (several months now), and just added CRS. While the RCS are breeding, I'm not sure that too many are reaching adults. CRS seem fine so far (only been 24 hours).
I just added blue velvet neos and CRS to the 2.6g (it is a newly cycled tank). A few of the neos died already, but the CRS seem fine.
Both tanks have exclusively RO/DI water remineralized with SS GH+. My question is, do I need to do anything to raise KH slightly in either or both tanks? I'm not sure if this would help the survival and breeding of the neos? The blue velvets aren't cheap and I would hate to lose them, but don't know if I should go messing with the chemistry quite yet. Obviously I am targeting primarily the needs of the CRS so far.
Thanks!
