Okay so I've had a 10 gallon tank with a divider to make 2 sides. One for Betta and the other for RCS. The tank is cycled and has been running since December 2016. I've had issues with my shrimp slowly dying off one at a time and I just kept buying more shrimp figuring that I would figure it out later. Well today I found 3 dead! Here's some reading from tank. I just don't have a TDS meter. Is it possible that this is what is the culprit the whole time??? Temp- 80 f PH- 7.6 ammonia- 0 nitrite- 0 Nitrate- 30 (Could this have done it?) (missed a water change here and there due to life circumstances) GH- 8 KH- 3 TDS- unknown, have yet to get a tester. I have 2 chunks of cuttlebone in there to help with calcium and I guess other minerals? If I can't get this fixed I'm giving up. I have had enough. which is very sad because out of all 3 tanks I have this one was one of my favorites.
