I have RCS in my 90 gal "algae eaters" tank. I'd call it 'moderately heavy planted'. Topsoil substrate, no cap, it's fairly sandy. I started with 75 shrimp about 6 weeks ago, they appear to be breeding since I've seen quite a few berried, although I have yet to see a real abundance of juveniles. I'm hoping it's just been too hot in this tank and they'll pick up now that it has cooled off a bit here. I moved 6 (4 females 2 males) to an established 10gal with christmas moss (all fish that were in the 10 went back in my community tank) so that I can closely monitor breeding. Hopefully in a few more months the colony will really take off in the 90, I'd love to see what a tank with 1k+ shrimp looks like.
From my Tetratest Laborett kit, I have not verified the kits accuracy, but I am positive I'm using the kit right.
GH (General Hardness): 1 to 4 degrees German hardness (most consider too low)
KH (Carbonate Hardness): 12 to 16 degrees German Hardness (most consider too high)
pH: 8.5 to 8.8 (most consider too high)
NO2 (Nitrite): 0
NH3/NH4+ (Ammonia): 0
No CO2, I may fiddle with some DIY, but I doubt I can impact my tanks much with it. Occasional Flourish when I remember.
I also have a 15 gallon planted with Süßwassertang and Taiwan moss that I started about 4 weeks ago, Eco-Complete substrate. Soon I will be looking for a second species of shrimp to keep in it on my new home office desk.
** Note that I'm in Waco, nearly 2 hours from Dallas. I intend to try to make a meeting though, I have friends in Arlington that I could visit in the same trip.
