Doc4PC2 Posted May 11, 2014 Report Share Posted May 11, 2014 Does anyone know why your KH would spike all of a sudden? Yet the PH is still low, and the GH is the same too? Temp - 72.5 F Gh - 4 PH - 6.2 - 6.4 TDS - 150 KH - 5 - 6 / usually it is 0 - 1 No ammonia, no nitrites, just a touch of nitrates I did a 50% water change, using just RO water and Bee Shrimp Minerals GH+, and some Borneo Wild Shrimp Shield Supplement, same temp, I ticked up the air stones and sponge filter to agitate the water some more I had two shrimp deaths. one CRS, and one CBS, both about middle size. The first two deaths that have I have had since I started, and the only reason I can see is because the KH spiked up, yet the PH stayed the same? I rinsed out my filters in aquarium water, did the water change, but it still says my KH is is around 4 to 5? When it normally is around 0 to 1? This is in my 10 gallon tank that is almost 3 months old now, and my shrimp have been in there for around 2 months. I even have two shrimp that are berried, and they have seemed to be doing just fine. I did have what I thought was planaria worms, but it was not, it was just some detritus worms that are not harmful to shrimp, and while there are still a few around, there are very few. I did a three day dosing of Fenben, which did not effect them at all, because I thought they were planaria, and turned off the lights for about 30 hours. I then changed about 30% of the water after that. The Fenben didn't seem to bother the shrimp at all, and I didn't have any deaths during this. But, really, the only thing I can think of is the KH is raised somehow. If a water change doesn't lower the KH, what would? Thanks for the help. I haven't put anything new into the tank at all. Everything has been the same, nothing introduced within the past couple of weeks. Quote Link to comment Share on other sites More sharing options...

Doc4PC2 Posted May 11, 2014 Author Report Share Posted May 11, 2014 I get 0 to 1 KH on my RO. should I try boiling it, let it cool down to 72 degrees, then add it? Quote Link to comment Share on other sites More sharing options...
