NeoCHI Posted April 6, 2019 Report Share Posted April 6, 2019 I purchased 20 RCS online from a reputable seller recently and they've been slowing dying...not sure why. I have them in a Marineland 5 gallon that I've put filter sponge in the back to block the inlet from sucking up shrimp. Here's a timeline of events: 3 months I did a 90% water change with RO water of this existing tank I previously had fish in preparation for shrimp 2 months ago I got my 20 RCS and add them to tank 2 RCS died about 2-3 days in Afterwards I've lost about 1 RCS every week. Somewhere in here did a couple micro water changes with my tap to increase my GH because apparently my RCS came from water with GH 8. 3 weeks ago I increased filter flow rate because it seemed a little low 2 weeks of no death 1 week ago I added 2 CRS Yesterday 1 CRS died Today 1 RCS died Here's my water parameters today: Temp: 74 PH 7.4 TDS: 180 Ammonia: 0 Nitrite: 0 Nitrate: 0 GH: 4.5 KH: 3.5 No pregnancies...just deaths...I'm down to about 10 now. Please need some help! Quote Link to comment Share on other sites More sharing options...
