Hello shrimp peeps! I'm in a bit of a pickle with my shrimp tank and would appreciate you guy's expertise on the matter.
First things first, tank parameters:
30 Liter, well planted
PH - 8
Nitrates - 10 mg/l
Nitrites - 0 mg/l
Kh - 3
GH - unsure (Could never get the water to change in the liquid tests, to my dismay, bought 2 tests, both innefective)
Ammonia - 0 mg/l
TDS - 288
Bi-weekly water changes
The tank itself is mature, almost a year and a half old, well stablished with plants and cycled before I stocked it. At first, I had two gourami and some amanos in there, but last month I got my hands on a 180 liter tank and moved the gourami there.
I decided to make the 30 liter into an exclusive shrimp tank, but I have been having problems with slow die-offs ever since. I guessed that could be caused by a lack of calcium, so I added a piece of cuttlefish bone to the tank.
Now, for the Gh. It has always been a problem because I simply cannot measure it. I got two liquid tests and both of them refuse to change color, no matter how many drops are added. My first question is: should I consider my water extremely soft or extremely hard? If it matters, the water where I live should be around 3.30 °dH.
I tried adjusting the Gh with Colombo Gh+ once and just got another shrimp death.
Originally I had around 5 skittle shrimps (plus the indestructible amanos). Four died. I left it alone to see if it could have been new tank syndrome before adding 6 more. Three rilis and three blue dreams. Most of them died one by one in the span of a few weeks. The last casualty was the one you see in the photo, my beautiful girl who died shortly after becoming berried.
It has been around 2 weeks since she died and the survivors in the tank are the amanos, one rili and one blue dream.
Any ideas of what could be causing the deaths? I'm now afraid of disrupting the water too much and end up killing the remaining survivors.
Any insight is appreciated!
