So, My tap water is around 6.5 and with my RO unit and Salty Shrimp my ph rests around 6-6.2. Because of this I can not get much breeding for neocaridina so Im moving to all Caridina. I have a new tank set up with just plain black sand, and my ph stays at the 6-6.2 range, just like it does with my tanks with a buffering substrate. So even if i try to get a high ph, I can't. Would you think its ok to put Caridina in the inert substrate tank given it keeps the ph low? what other issues could there be? Also, my tap has too much ammonia is kills the shrimp even with prime
